Its a really concept, and I dug the aesthetic, especially all the little icon! I did have some problems with mouse control, however. I found it a little frustrating, especially when you needed to perform precise jumps, like in level five. Also, the screen wrap doesn't work when there's an enemy on the opposite side, as your character ends up running into the enemy because your cursor is still on the other side.
Other than that though, it was pretty fun. Nice job!
