In the hub, there's a background music: After the girl told me to restore the happiness, the hub music started; and after I find the hope of the true ending, the hub music changes. https://jimmymaslaki.bandcamp.com/album/happy-world-soundtrack But why don't you upload the hub musics to the soundtrack? 


https://jimmymaslaki.bandcamp.com/track/burn , what's burning in the game? 


Red, you, burning in pain

Does it play when doing the true ending?

Yes, before you enter the furnace if you fall off it will trigger the event

Finding the true ending was too easy for me. If you wanna make it difficult, modify the way to get the artifact from purple, blue, or red. E.g., to press the space(while not talking) is to dance, it's difficult to get the artifact if the player must dance in red plane. 

I don't have the project anymore, it's on my old harddrive that crashed

Had a blast playing this one! (forgot to post when I first played it) 


I was absolutely loved this game, I watched ManlyBaddassHero's playthrough. I must say I absolutely loved the music elements especially the worm zone. Would you ever upload the soundtracks on Youtube or Soundcloud?

(1 edit) (+1)

Thank you very much : )) it used to be on YouTube but my former channel was deleted. A lot of the songs were uploaded on my old soundcloud which was also deleted. But the entire soundtrack is available for free on bandcamp : ) https://jimmymaslaki.bandcamp.com/album/happy-world-soundtrack

I'm guessing you already saw but just making sure.


Thank you very much! I'll make sure to check out your bandcamp. (^-^)


This game is quite charming! It reminds me of Petscop and LSD Dream Emulator. I did get quite the scare on my first playthrough. Overall, I really enjoyed playing this game, as well as your other works!

Thanks :)


This game fuckin rocks but I can't enter purple, is that intentional?

also by that I mean I try to get into purple (3rd furnace orb) and the screen does the transition flash, but I don't actually move

Thanks :) and that's weird, what version did you download? I've heard that the mac version is glitchy

I have the windows version, should I try redownloading the game again?

I'm sorry you're having this problem. Seems to be corrupted, I would try redownloading the game. Fortunately you don't have to restart, you should still have all your progress.

I downloaded it again and played it, and the same thing happened. Is that what you meant by redownloading?


I loved this game. I played it on my YouTube channel. Hope you don't mind!


got petscop vibe from this game, do you happen to know petscop? 



Hey im in love with this game and the soundtrack is there a way i can buy the soundtrack

Hi, thank you! You can get the soundtrack for free here :)


wow thats really amazing the ost is so good i love it

can we do full screen??

Yes, you can do Alt+Enter to toggle full screen and also F4 I think



You're welcome!

Jimi Masuraki the troll :D

hello friend!! i just finished my first playthrough last night and it was very spooky, i love this. the writing is amazing and the aesthetic/art-style are right up my alley!! i do have kind of a silly question though, if u don't mind. is there a way to avoid making nunu cry? i love her so much : (

thank you! and yes, if you do the true ending, you can skip all world 3 missions which includes nunu. you can still visit her though

i see!! thank u so much for your zippy reply!!

no problem! i just got on the computer haha

Holy shit, this game has grown! Since 189 days (Its launch), this game has become pretty popular. Great job, Jimi/Jimmy!

Thank you :)

Hello, I can't seem to run the mac version, it says it's broken :(

So I haven't started this yet, but is this different from Happy Zone? Do I need to play one before the other or does it not matter?

Yes, it is different

No it does not matter which order you play it in. Have fun :)

I've played through world three, but now I only have access to the destruction ending. Is there a way to restart the game?

If you do that ending and open the game again it should have reset. If not, then you can restart it by going into app data and deleting the .HW files in C:\Users\Username\AppData\LocalLow\Jimmy Maslaki\HAPPY WORLD

Thank you, Mr Jim. However, I believe you are referring to the Windows version. Can I do this via apple?

Knock over tables to make the nunu cry and kill the guy by giving him a match . Is that rigid ? I played the game several times , but I cannot change the rule that makes nunu cry and kills the guy . I saw sad camp is opened and I can go there without answering the competitor, is it a bug ? 


I have a further question . Most of the places have their names, such as excland ,snow zone, nunu bakery  . But some places don’t show their names. I got the key from purple slime and went to Hub , I don’t know the name of that place . Please wait until the song ends in snow zone and it will take you to a secret place which is in happy zone . I don’t know the name of that place . 

If you do the second ending and get the RED PLANE artifact you can skip world 3 missions.

And the purple slime key place is called Plasma Hole

And that last place is called "HAPPY ZONE"

Someone’s baking a pie in the house. Is there any way to ask the man who’s baking a pie come to happy party ? Or the happy party is vacant . 

Nope, there is no way.

I'm pretty sure Happy Party Enterance is a tease at the dev's next game, which is also called Happy Party, i'm assuming that interacting with the MACHINE in that area will bring you to the page for Happy Party in a future update.

It already does bring you to the page. But it will also bring you to a new level in a future update(probably).

You are very good at using sound effects and music to create an atmosphere, and also at


spooking me

This game has been mentioned and recommended by itch webmasters. . https://itch.io/blog/21258/itchio-recommends-impossible-experiences  . 

The game is a fun adventure through a colorful and fun environment!

All the characters are what made the experience complete for me!

By far one of the few hidden gems on this website :) 

You may knock on the door in world three and three rooms are vacant . You’re wrong and one room isn’t vacant. There’s someone dancing in one room , but the piano plays more loudly than  you knock on the door or someone answers you . You should keep him from playing the piano and you will hear someone’s dancing . 

Great game! I love the whole DDLC/Petscop vibe and the secrets in the files. I think I found everything on my first playthrough but wanted to know !!!SPOILERS!!!

 wether it is possible to find the "plasma hole" and fix the reincarnation filters or find the skinless womans mind in excland?

thank you! and yes it's possible, you still haven't achieved the true ending, you need to go to plasma hole indeed :)

on another topic, Excland is pointless. i just made it for fun

There’s a book myth of the skinless woman in the shop zone . Is it just decorative or something useful ? I tried every key on my keyboard , but I cannot see the book .

The guy pn the right in shop zone will tell you how to read the book. !!!SPOILERS!!!

 It's in HAPPY WORLD_data and it's called motsw.txt

There’s someone eating an ice-cream in the snow zone. Since the bottom of the cone looks very sharp , I want to ask a question. Is that possible to get the ice cream from that guy and dig a hole into the ground ? 

How Though??? I've talked to every singe character and done every possible thing. I did everything I can and got the artifact from each plane. !!!SPOILERS!!!

The only things left are the locked orb behind the house in world 3, the bird house on top of that house and the reset man(does he actually restart the game or is it a DDLC kinda restart?)

He actually restarts the game. And try talking to purple slime by the motel

(1 edit)

!!!SPOILERS!!!(should be obvious by now XD)

Thanks! I saved Skinless Woman and Purple and then the DDLC music came on and it all became clear XD Is the Skinless Woman Monica? And is Purple Sayori? And Red could be Yuri, because death by stabbage or Natsuki because of anger( although Natsuki isn't that psycho kind of angry, she ist waifu) and so Blue would be Natsuki then. Was this intentional or am I just wrong? Either way it's great!!! But does saving certain ghosts change the blue machines response?

It's just a coincidence. And oh, thanks!

And blue machine can't do anything else.

I’m very sorry about I posted the reply before literally trying every key on my keyboard . I tried to press D , I will see the book . https://gurusability.files.wordpress.com/2014/03/navigation-keys_thumb3.png     . This is why I’m unable to find the book , I use them instead of W S A and D . By the way , this is one of the reasons that I think happy zone is worse than happy world . Because happy zone doesn’t support these four keys . 

I can get to secrets or get artifacts in somewhere , their musics only perform once . But the musics of other places are looped , does it mean I cannot find any secrets ? 

I play this game much earlier than downloading  the previous project happy zone , I don’t know anything about the early  events of the multiverse. I recently downloaded happy zone to see the past events of the multiverse  , but the quality is worse than happy world . For example, I only helped few people and the game told me I can go now 

This games a lot of fun and very cute! It definitely surprised me a few times as the game went on too. Lots of secrets, cute art and a fantastic OST. Definitely worth checking out.

There’s a pink thing on the question-marked platform in the snow zone. If you find the secret before giving the pink thing to the machine, you can only see the skinless woman. If you give the pink thing to the machine before entering the secret, you can see both the pink ugly thing and the skinless woman . So I guess the machine can put things into the secret which is the ancient place in happy zone . 

Very interesting game! I have played the game once, but I know there is still a lot I am missing! Im on my second playthrough now, trying different things and I keep finding more and more little details I missed on the first playthrough! I reccomend this game! (You may want to play during the day if you are easily frightened!)


This game had a super nostalgic “PlayStation classic” feel to it. That paired up with some Petscop and DDLC vibes easily makes this one of my favorite indie games right now. It definitely needs to be bigger than it currently is. Multiple endings, lore, Easter eggs in the files, and other stuff that I don’t wanna say due to spoilers. 

Character movement was a little touchy and it was hard to stop moving in a certain direction once you gained some momentum (this caused me to fall off the edge a lot) but other than that, I didn’t want to put this down! Thanks for making this game!! Please make more like it!

Okay, so I definitely missed a TON of stuff in my first playthrough of the game. I did a quick episode digging deeper and achieving the alternate 'ending' - I tried to find all of the secrets that I could in this one. I know I missed stuff, and have gone back and unlocked even more! One more video coming tomorrow!

This game just keeps astounding me with its deep lore and secrets. Even now, watching my videos on this game, I'm seeing things that I didn't catch the first time. Little bits and pieces of info between characters are tying together. It's brilliant. If I was a theory channel, I'd SO totally do a theory on this game. Thanks a ton for making this!

This game was so immersive and it had so much information hidden. Just have to dig deep and pay attention to what the NPCs say. It's not ALL nonsense. That being said, I think I found the rest of the secrets in this game!

Here's the second part to my playthrough:

This game is so weird...
(1 edit)

You didn’t find the true ending or secret places. The most obvious secret is the party in restaurant zone, this is the most obvious secret but you didn’t enter it . There’s a bouncy faraway, no floor and no ground  holds that bouncy, that is the entrance of the party . 

The latest release doesn’t contain a frog ? Probably, demo version contains a frog 

The frog is unlockable in the full game. But it's a secret.

(1 edit)

I saw something that’s shining but isn’t very bright  in the plane after the song ended. I took the artifact and then the brightness disappeared . The brightness was near the place where the ghost was living on . Either my computer screen has some problems or that’s the scret place of the frog . Excepting the screen problems, I need to know how to let the brightness appears again because I only did it once when I was arbitrarily playing the game. 

There is no brightness, I believe it's just your computer screen

It proceeds me to play the game in any dark rooms, and not to turn on the lights.  If I turn on the lights or play the game before 18 o’clock , it will make me see something wrong on computer screen

Alright, the tune when it said there was never negative energy and then showed a machine... And then showed my real name. You pulled a DDLC. I'm impressed. I expected it, but I loved it. The goosebumps, the amusement.. It also gave a Petscop feeling, due to background, interactions and few other things.

Why didn’t you upload a video to YouTube ? 

Thank you :) it pleases me to know people actually get goosebumps from it

That effect was definitely amazing, the sound effect coupled with the window size change, as well as showing my real name definitely made me jump, to say the least.

This is quite frankly, the weirdest game I've ever played. Thank you for that.

Here's the first part of my playthrough, if anybody's interested:


I thought I played through the entire game, but some of the screenshots are unfamiliar to me. Did I miss something? I did see there was a (locked) secret world teleporter in world three, but after the ghost-lady in the hub ended the game for me, I just assumed it was over...

Oh okay, thanks for the information, I'll probably check out the secrets I missed in a second playthrough :D

The competitor of nunu bakery told me to knock over tables. Do you have any ideas to make both the competitor and the nunu happy ? 



...but I have many feelings about this game ._.

Most of which are positive, though! I am however, a big puss. Quite a bit of what I saw iyour game scared the bajeezus out of me, and I don't handle that very well... (my mind kept going back to the fire guy and the "don't leave me" room when I tried to go to sleep 2 nights ago >< It was not pleasant)

That said, while I don't aim to continue playing it after...well, THAT...I enjoyed the experience, and definitely recommend others play it for themselves ^^

I covered the game twice on my YouTube channel. Next episode's going up tomorrow morning. While I can't handle playing more of it myself, I do hope this helps encourage others to give it a shot.

excuse me but why did you put my patreon page as the thumbnail and call it $71 per month? it's a free game. and if not why are you saying how much i make on the thumbnail?

Deleted 263 days ago

Why do you feel uncomfortable ? No, I don’t 


i mean nothing bad by it but, what is going on with this world?!!

ty for playing but just an fyi, it's not a puzzle game

How do you categorize puzzle games and non-puzzle games ? 


well you see, puzzle games have puzzles in them

and non-puzzle games


I thought puzzle games were the ones without the puzzles

now i'm confused

Merriam-Webster dictionary says puzzle is about solving problems. And the game happy world has secret places and the problem about what you should do in blue plane . But the developer doesn’t think it’s puzzle game , why not ? 


 just... why...
