Stolen Heart (Prototype)

Stolen Heart is a cooperative roguelike where your mission, yours and your friends', is to protect and escort… a living Heart.

Fragile, unstable, essential. And its BPM is your shared countdown.

Together, you'll navigate a laboratory ruled by AI-driven robots, manage the Heart's pulse through a cooperative rhythm mechanic, and survive a dizzying descent toward the Earth's core.

Each run is a race against mounting pressure, where coordination, timing, and mutual trust determine whether you make it out alive. Every beat counts. Every decision resonates, literally.

A Heart to Escort… and to Play

The Heart is not an item. It is a playable character: vulnerable, emotional, but crucial to the team thanks to its unique abilities.

And its BPM is the threat you all share. As enemies close in, its rhythm accelerates. Let it spike too high and it's the end for everyone.

The player embodying the Heart holds a decisive power: revive fallen teammates, weaken enemies, or empower the whole squad during boss encounters. Every decision shapes the outcome of the run.

Protect it, sync with it, keep its emotions under control: that is the core of the gameplay.

A Unique Cooperative Rhythm System

When the Heart gets stressed, its BPM rises.

Players must then synchronize their actions to its beat in a shared music-based mini-game:

Chain actions at the right moment as a squad to unlock powerful buffs
Miss the timing window and face the consequences
Let the BPM go into the red… and the run ends for everyone

No soloists. Either the whole group holds the rhythm, or nobody makes it out. Every fight becomes a race against the rising pulse, a collective tension, beat after beat.
