I really loved this game and its idea. I don't mind the simple graphics, but I think the movement needs a bit of a tweak. Since I could not aim where I wanted to go (the movement is always kinda the same distance), I died many times by failing to calculate my trajectory. I think if you were to move to the mouse position (with a distance limit, of course), it could be easier to plan and even more fun.
Great, great work :D
