Solve the mystery of the facility

Bittersweet Birthday starts with you waking up inside a rundown facility with no memories. You’re greeted by a voice named Ada, who says that they’re currently locked up inside one of the control rooms to protect themselves from the people currently hunting them. You’re also a prime target, and Ada suggests that the two of you team up to escape. You’ll have to find them, however, and survive encounters against strange enemies.

This game offers a punishing bullet hell combat system that requires you to pay close attention to your opponents’ attacks. Similar to Enter the Gungeon and the Touhou Project games, you have to evade attacks that continuously fire for a set amount of time. Every encounter is an intense one-on-one duel where you study your enemy, master their rhythm, and navigate multi-phase attacks blending Souls-like precision with bullet hell chaos.

The story switches between the present time and flashbacks of forgotten memories. You’ll spend plenty of time in the flashbacks, exploring the past when your life was still peaceful. You’ll get to meet a colorful cast of characters, and the plot really enticingly dangles the mystery of the facility and why you can’t seem to remember anything. Additionally, you’re given the option to remap your controls for both PC and console devices.

Practice makes perfect

Bittersweet Birthday offers a compelling mix of challenging bullet hell combat and emotional storytelling. As you fight to escape the facility and recover your memories, you’ll uncover intriguing mysteries and meet a quirky, charming cast. The real-time battles demand precision, while flashbacks add depth and heart to the narrative. With nostalgic pixel visuals, customizable controls, and fun Gachapon collectibles, this adventure delivers a rewarding and memorable experience for action and story fans alike.
