Reviews

“Bittersweet Birthday is a fantastic choice for fans of challenging action games who appreciate a tight, modern take on retro design. If you’re looking for an unforgettable, sugary-sweet adrenaline rush with depth far beyond its cute exterior, go grab a slice of this birthday cake.”
The Daily Gamepad

“Bittersweet Birthday is a reminder of why indie video games remain the most creative soul of the medium. With brilliant art direction, a demanding combat system and a story full of symbolism and emotion, World Eater Games has made an outstanding debut.”
9/10 – Generacion Gamer

“Bittersweet Birthday is a bold and cohesive package that will strongly appeal to players who appreciate a rigorous challenge wrapped in a captivating narrative. Its unique boss-rush structure ensures consistently high-quality combat, while its thoughtful exploration and quirky characters provide a rich emotional counterpoint. The game is not for the faint of heart, as its difficulty can be punishing, but for those willing to embrace its chaotic combat and unravel its dark secrets, the reward is an unforgettable journey through a world that is both terrifying and tender. It's a testament to how tonal shifts and focused game design can create a truly distinctive experience in the indie scene.”
4.2/5 – OMEGASCOPIO

About This Game

You wake up in a strange facility with no recollection of who you are or how you got there. That is, until a voice calling themselves ‘Ada’ on the other end of an intercom warns you that you’re being hunted, and promises to help you escape.

Bittersweet Birthday is a story-driven action-adventure game where every fight is personal, every victory hard-earned, and every clue a step towards uncovering the truth lying somewhere inside the miasma of mysteries.

Each encounter is a one-on-one showdown with one of your nemeses. Read your enemy, master their rhythm, and adapt to their patterns that blend Souls-like precision with bullet-hell chaos. Punch, kick, block, dodge and parry your way through multiple phases that feel like a final boss each time.

Tweak the challenge to your liking through the Memory system. Memories are gameplay modifiers directly tied to the character’s pasts. They can make fights easier or harder, but never trivial.

Between fights, catch your breath in a vibrant village full of strange and endearing characters. Complete side quests, dig into local mysteries, and enjoy a surprising amount of heartfelt (and often ridiculous) downtime.

Try your hand at darts! Or well… I guess darts are partially used, at least.

Hunt down all 48 Gachapon collectibles, each one of the cool, cute, or creepy kind!

Hand-drawn pixel art and detailed backgrounds bring every memory and location to life.
Fully remappable controls with support for PlayStation, Xbox, and PC controllers.

A STORY THAT LIVES UP TO ITS NAME

Bittersweet Birthday mixes psychological horror, sci-fi mystery, and dry humor into a story about identity, trauma, and what it means to move forward.

Some truths are hard to remember… others, hard to forget.
