Your world is bombarded by multi-colored asteroid spheres and it is only pleasing that they fall in a strictly defined place, and this inspires hope that great destruction can be avoided. On the path of the spheres we will put a sharp tower, similar to a pencil. Your task in the Spherestroyer game is to click on it to change color depending on which asteroid falls from above. The color of the tower and the stone must match so that it collapses. You need a quick reaction and attention so as not to miss the moment of color change.
