About this game

Bittersweet Birthday overview

You wake up in a strange facility with no recollection of who you are or how you got there. That is, until a voice calling themselves ‘Ada’ on the other end of an intercom warns you that you’re being hunted, and promises to help you escape.

Bittersweet Birthday is a story-driven action-adventure game where every fight is personal, every victory hard-earned, and every clue a step towards uncovering the truth lying somewhere inside the miasma of mysteries.

Each encounter is a one-on-one showdown with one of your nemeses. Read your enemy, master their rhythm, and adapt to their patterns that blend Souls-like precision with bullet-hell chaos. Punch, kick, block, dodge and parry your way through multiple phases that feel like a final boss each time.

Tweak the challenge to your liking through the Memory system. Memories are gameplay modifiers directly tied to the character’s pasts. They can make fights easier or harder, but never trivial.

Between fights, catch your breath in a vibrant village full of strange and endearing characters. Complete side quests, dig into local mysteries, and enjoy a surprising amount of heartfelt (and often ridiculous) downtime.

Try your hand at darts! Or well… I guess darts are partially used, at least.

Rock, paper, scissors – fighting game edition!!

Hunt down all 48 Gachapon collectibles, each one of the cool, cute, or creepy kind!

Hand-drawn pixel art and detailed backgrounds bring every memory and location to life.

Fully remappable controls with support for PlayStation, Xbox, and PC controllers.

A STORY THAT LIVES UP TO ITS NAME Bittersweet Birthday mixes psychological horror, sci-fi mystery, and dry humor into a story about identity, trauma, and what it means to move forward.

Some truths are hard to remember… others, hard to forget.
