ABOUT THE GAME 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. GAMEPLAY Bittersweet Birthday is a story-driven action adventure 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. HANG OUT 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.
