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 party.

Bittersweet Birthday is a story-driven action RPG where every battle is a 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 mementos that shape your fighting style. 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.
