Whew! This is hard as petrified stone, but it's a really nice starting design with pleasant graphics. WASD + space was a bit awkward for me, i might suggest WASD + mouse button? Though maybe the mouse has user later on, I dunno. Also, I wasn't getting any audio.
I could NOT make it very far at all, but I do suck at this sort of game. I suspect it's probably a bit too hard for most, at the start. Great job submitting (next time make sure to get an image, even just a screenshot- i think you're not getting very much traffic because you forgot the image!) good luck!
