This is a game that I am working on at the moment. I got the idea from a game that I played on the web somewhere.
The objective of the game is to pick up black squares while avoiding the red squares. As the black squares are picked up, the green disc that the player controls with the mouse will grow in size. The frequency at which new squares are introduced will rise as well as time goes by to make the game more difficult as it progresses.
The expanded mode adds on powerups where blue squares provides different advantages. I am still working on adding more powerups, but the regular mode is finished.
