Bittersweet Birthday DEMO
A downloadable game for Windows, macOS, and Linux
Full game coming Q4 2025! The Bittersweet Birthday demo showcases a slice of the game’s challenging boss battles, exploration, and heartfelt storytelling. Experience its unique blend of brutal challenge and charm today! 
You awaken without memories, disoriented and alone, until a mysterious voice over a speaker offers you a way out. Hunted by unstable pursuers, your only chance at survival is to follow its cryptic guidance.
Along the way, you’ll piece together fragments of a past scarred by trauma, confront truths better left forgotten, and discover why the path forward leads to one unavoidable destination: your birthday.

Bittersweet Birthday is a story-driven action adventure game where every battle is a major boss fight, each one a unique, challenging test that blends “Souls-like precision” with bullet hell chaos. Survival means mastering enemy patterns, timing your dodges, and striking with precision in battles that demand both patience and nerve.

Outside combat, you’ll explore a bustling town, uncover secrets, complete side quests, and collect dispersed memories that can alter the level of challenge as you see fit. Packed with an eccentric cast of characters, nostalgic pixel art, quirky mini-games, and even collectible gachapon, Bittersweet Birthday offers a blend of punishing challenge and heartfelt charm unlike anything else.

Install instructions
For Mac, if you try to open the game it will get blocked by the OS. You'll need to go on the Security & Privacy window, General tab, and click on open anyway.
On windows, you'll probably need to allow it to "run anyways", as it will probably detect it as "unverified developer".

I had fun playing this — short but memorable experience!
acabo de terminar la demo y literalmente estoy temblando, cuanto tiempo aproximadamente tendríamos que esperar para tener mas porque no puedo esperar para seguir jugando
Jjaajaj gracias por el entusiasmo, tendremos noticias pronto!
No plans for Android?
Yeah, that's not in our current plans.
The fight had me tilting hard, but after a week-long break, it wasn't actually that bad. After completing the demo, I'm definitely looking forward to the full release! Great game!
The first boss is already driving you crazy...
Three phases, no health regeneration, do whatever you want...
Good game but the difficulty curve is so steep
This game is overall really fun is it still being worked on? Haven't heard or seen a lot of people talking about it lately.
Hey! The game is most definitely being worked on! We are just a quite bunch lol Glad you liked it (:
if i attempt the FIRST boss again i might lose my mind
i love this game so much but i cant beat the first boss :( i've tried so much haha we'll get it sometime thoooo......
stuck here between two shops, easy to reproduce. hopefully saved game before.
I really like the game, but I can't defeat the first boss no matter how many times I try...
But I was stubborn and persevered, tho to no avail.... I died so many times there, more than I'd like to admit ig.... o(TヘTo)
i got stuck between the stalls :(
Oof, sorry about that! Which ones specifically if you don't mind?
left to right, top to bottom, the 1st and 2nd stalls
windows 32 bits version maybe?
I really love how polished the game already is, especially from an animation and UX point of view. I struggled a LOT with the first boss though, it's painstakingly difficult for a tutorial level, even if you know the patterns... you really have to hope you can pass the "see if you can dodge this" phase with enough HP to survive the rest! I noticed in one of Rocc's first appearances, he's identified as Rocc and not "???". There's also a typo in "existence" in that scene:
Great work, and congratulations for doing it with Godot - really excited to see what comes next, and this will definitely become a quality target to meet for my own Godot games.
Literally made an account to comment on how disappointed I am.
Everything is praisable except for the attack patterns. You can tell that the devs don't know what they're doing in that regard and just saw a bunch of fancy bullet hell games with actually complex thought-out patterns and decided to chop up all of those ideas to make one Frankenstein spaghetti pattern.
It genuinely baffles me that the developers decided to combine very fast-paced attacks that require you to maneuver the battlefield with attacks that limit where and how you can move. Get very used to dodging widespread, directed, randomly generated, and lasting attacks that disrupt the battleground all at the same time with no way to heal! Don't forget you have to multitask that while attacking the enemy or else you can't progress!
Disappointed, because everything else is great except for the main aspect of the game, which is the gameplay.
EDIT: I take back everything said above, you can pet the dogs.
So:
POSSIBLE SPOILER ALERT, DON'T READ IF YOU'RE NOT INTERESTED IN KNOWING WHERE THE SECOND MEMORY IS AND WANT TO SEARCH FOR IT YOURSELF
To get the second memory, you have to go back to the place where you first woke up at the start of the game ( ^◡^)
Hiya I gave this a try and great job on your goal
I did a video....Wow that boss battle
Keep up the great work.its a bit confuzzling how it takes the calm gameplay at the beginning and then thrusts you into an epic mega boom boom kablam boss fight, but otherwise sheesh 10/10
Yep, this is fire
hey is the a way to unlock the second memory in the demo or not?
Yup, just gotta be reaaaaally thorough and do some backtracking (:
nothing got it did right thing but at wrong place
I cant defeat the bird in the first boss battle but i feel like its a great game
hey!! that ending!!!! wasnt okay!!!!!! my poor heart ç-ç and now i gotta wait until the games done??? yall are cruel!!! the game is awesome but yall are actually cruel!!!! pls say syke right now let them be okay ç-ç
The story has already got me hooked and I can't wait to find out more . Tip: make sure to check on the teddy bear in the hospital wing, it might be lonely ;)
I'll admit I had a really hard time with the boss level, and I felt a little better seeing the comments that others were too, so at least it wasn't just me. I have a whole second episode that is just me failing over and over (still not beating bird guy) but I feel like it's still doable. I'm getting the impression that this isn't about grinding experience and preparing for boss fights and more about learning fight patterns to just barely scrape by. So it may take a few more trys than anticipated but boy, will I deserve that win when I get there.
I also got my titles mixed up and just realized this game goes on after this fight, so this may become a bit of a series for me, haha. Can't wait for the full game to come out! Good luck World Eater!
So I just started playing this yesterday and really like the atmosphere it set right off the top. "Abandoned Lab" theme has been one of my favorites since I was a kid.
The is one kick ass mask the person on the title screen has! I was like, "Holy cow!"
I really liked the demo of this game! It was so cool! Are you guys working on the full game soon?
Yup! We just got funded on Indiegogo and have already started working on the rest of development! (:
Please make for android
i’m quite intrigued by the ending..
I'm glad you liked it!! (:
Sad no android :<
Hm that's weird. Is your device 64-bit? If it is could you please try to download the game from the itch website rather than the app and see if that works?
ok ty
Does it work on 32-bit devices?
Not the current build, sorry!
Oh well it's okay
i really think this game is cool
Just beat the first boss with controller! I love the challenge & where the story is going. I can't wait to play the rest~
omg this game it's so beatiful
how is everyone saying its excellent the first boss is impossible when A and D are literally disabled
Hey!
You weren't able to move with A and D? That sounds like a bug...We'll be checking it out.
Sorry about that.
Excellent!
Last video again
just finish the demo this game is really difficult and fun both at the same time looking forward to the final project :D
The next video
Made another new video
