Nice work! Some of those levels were fiendishly difficult if you wanted to get all the cherries and make it out in time! I actually got pushed into a wall by a platform in one of the stages and couldn't wiggle my way out but up until then I was really enjoying the finesse required to either sprint or not when jumping and wall jumping.
Great aesthetic and a pity we couldn't get it to work on Geekfest night. Bizarre error message, I'm betting it was due to those laptops being pretty old :S
