This is an arcade-style shooter game. At the bottom of the screen, there is a spaceship that you control to fend off incoming objects. Your objective is to destroy all these objects before they reach and touch your ship.
The objects appear in various colors, and you can only destroy them by shooting with a matching color. Some objects require multiple hits to be eliminated; the number of shots needed is indicated on each object. If you hit an object with the wrong color, its hit count increases, making it harder to destroy later.
To switch colors and fire shots, tap on the left or right side of the screen. Tap anywhere on the screen to start playing.
