Heartseeker is a fast-paced platform-style puzzle game set inside a living dungeon that pulses with a heartbeat rhythm. The player embodies the Heartseeker — a sword with a hero's soul fused into it — that must be cast through twenty-one hand-crafted levels of spikes, platforms, and doorways. Each click strikes the blade into a wall, ceiling, or floor of the dungeon. Striking true means making precise, rhythmically aware decisions every fraction of a second. The goal is the heart at the center of the dungeon before it consumes all worlds.
