Impressed with your game, great job! Here's my little feedback: the mechanics of the long jump were not obvious to me the first few levels, I just pressed the spacebar and immediately released it, because of this I often fell. Also the level design in some places was such that because of the misclick you could fall back to the very beginning and this was disappointing. Overall, incredible work, I'm looking forward to your game in full format, with a plot and all that stuff :)
