Untitled Arena Game

An untitled arena game I'm working on for a competition on the Dutch Game Maker Community, the 49th Game Maker Competition. The theme for the competition is that you can only use 5 different colors. The deadline is 4 november, so I'm trying to finish the game before then.

For more information on the competition (in Dutch) check here :
