I really enjoyed this, looks wonderful, had no real issues with the controls even though I was using my laptop track-pad instead of a mouse.
I came across one slightly frustrating bug, the second jump I made right at the beginning I got stuck, mid-air on the corner of the step. It's quite tricky to reproduce, but it would be a shame if someone got a bad early impression. I've attached an image of where it happened.
I would be happy to do some QA for future updates if you need anyone to give it a good bash, just send me a message on twitter or something. :)
