Not a huge platform player these days so didnt expect to do well but I did better than I thought. The jump would have been better (more forgiving) with some edge detection for the player as the movement is very touchy and I was able to make mistakes very easily. The background music volume is also quite loud, I would prefer to have to turn it up than down.
Level design is really good, if I have any comment there it would be to tone down the difficulty a little in the 2nd and 3rd levels, give us old folks a chance to keep what little hair we have left and feel awesome for almost half a game, then crush our dreams :)
