Move the indigo box with the arrow keys and avoid the magenta for as long as possible. The magenta ovals will move around while the magenta squares will disappear and reappear.
Credit to @SPWAG133 for the original project and DSI Games for the music from Uno 52 used. Note: this version now creates start positions for the ovals, adds disappearing and reappearing features for the squares, adds music, and a game over screen with a timer score function.
