Bittersweet Birthday Premieres New Trailer and Confirms November 11 Release Date on PC

From intense battles to heartfelt storytelling, Bittersweet Birthday is a boss fight-only action adventure unlike any other.

Osaka, Japan – October 7, 2025 – Developer World Eater Games and publisher DANGEN Entertainment have announced that Bittersweet Birthday will launch on Steam, GOG, Humble and itch.io on November 11, 2025.

Bittersweet Birthday is a unique blend of brutal, finely tuned boss battles and heartfelt storytelling. Every encounter is a one-of-a-kind fight with multiple phases that demands mastery of movement, timing, and quick thinking, while exploration between battles reveals a world full of secrets, side quests, and colorful characters. Alongside its challenge-driven gameplay, the game stands out with its hand-drawn pixel art, memorable cast, mini-games and an atmosphere that seamlessly balances intensity and charm.

The teams have released a brand-new trailer that reveals new gameplay, cutscenes and focuses on the protagonist's third central nemesis, Cerie, a ghostly lady who resides alone in a crumbling mansion on the outskirts of the Guardian's village.

Boy (protagonist), a young prisoner with no memory of his past. Guided by a mysterious voice, he must escape a mysterious facility where he is hunted and piece together his identity.

Rocc, the Guardian of a secluded village, a hothead who must always be prepared to face the wrath of the Great Evil, a being that once nearly destroyed humanity.

Vega, the singer and guitarist of Metal Fang, a band performing their retirement concert in the Guardian's village. No one knows how they managed to bypass the centuries-old mandate of isolation, but the setting certainly suits the stage.

Cerie, a ghostly lady who remains the sole resident of a crumbling, long-abandoned mansion on the outskirts of the Guardian's village. Not even death can wipe the smile from her face, though it hasn't spared her from other, less pleasant emotions either.

How the Boy encounters these characters and what mysteries their relationships hold to the protagonist are up to the player to discover, if they can!

Bittersweet Birthday launches on PC on November 11, 2025, with console versions to follow at a later date. The updated demo is available now on Steam, where players can sample the hard-as-nails action, meet its eccentric cast, and prepare for the birthday of their lives.

About World Eater Games

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.
