The music selection is really top notch! Got psyched immediatelly..
The loading times really kills it though, at least on the web.. It's seem like there's loading time after you lose, and before you start a new run. This kind of game should be insta retriable.
I will give it a try in the downloadable version maybe, because there seem to be lots of effort here, and it would be a shame to miss it. Awesome work!
