i like it
simple yet fun
only thing else it needs its different sprites for the awesome upgrade, maybe some music so the gamer doesn't get totally bored, and some background choices or maybe a custom background for the gamer to upload or create their own custom background, and also make a boundary on the walls of the game so the character in the game doesn't disappear and never to return...
all in all: a good game.
rating: A good solid 3
not bad ... in fact i like it!
