About Bittersweet Birthday

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.

STORY
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.

About World Eater Games
World Eater Games is comprised of a small team of developers based in Panama. Though not a direct inspiration to Bittersweet Birthday, a few of their other favorite titles include NieR: Automata, Bloodborne, the Tales of series, Xenogears, Final Fantasy IX, and Kingdom Hearts II Final Mix. Bittersweet Birthday is their first major game development project.

“The main inspirations for Bittersweet Birthday are the earlier Monster Hunter titles, The Legend of Zelda: Majora's Mask, OneShot, Undertale and Hyper Light Drifter. These (and many others) are games that either through gameplay, story, or some x-factor have made a home deep inside our hearts. We are eager to share an experience that people can fall in love with and carry within themselves the same way,” says Ricardo Noriega from World Eater Games.
