About Blackhole Maker

Blackhole Maker is a game about building and merging a universe, starting by summoning a small stone. You grow it larger and larger until you create a black hole.

Summon and merge

To summon an object, press the spacebar when the moving bar overlaps the color in the lower area. You then build and merge to expand your universe.

Fever Mode

Pressing the spacebar fills the Fever Gauge. When it reaches its maximum, Fever Mode activates.
