Deep in the void sleeps a little core that dreams of becoming a star. Once in a while it flares awake for a single heartbeat. Catch that heartbeat, and it shines a little brighter.

How to play

1. Watch the dark core. The moment it ignites, tap the screen or press Space as fast as you can.
2. Tapping before it ignites loses the round.
3. Five rounds — faster reactions earn more points.
