I was not able to get it to work on my mac but it did work on my pc. I like the powerups and the level design, and the whole idea in general. The tune was catchy. The background and wall tiles kind of looked a bit boring to me. I can understand not wanting to spend too much time on them in a jam environment. also the knuckles type wall climbing power had some issues for me. sometimes the character would point the wrong direction when attached to the wall.
