Really aweseome experience, the whole movement system felt like it had lots of options and I loved how the mechanics built on top of one another. A couple of caveats: a platformer like this, especially on the harder levels, will have lots and lots of retries, so having the loading time cut down to a tenth of what is was now would've been way more satisfying (think of Super Meat Boy's reload times, it's basically instantaneous). I also got quite surprised when jumping to the top of the level killed me, I would have like seeing that somewhere in text or in an earlier level.
I also really adored the lighting, color scheme, sound effects, and the text in the background which all looked really polished and cool.
Amazing job!
