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.

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.
