Cool start
A couple of little things.
1) Occasionally generates platforms that can't be reached. Say platform 1 is Far from platform 2, but platform 3 is just a teeny bit higher than platform 2. It's impossible to make the double-jump work there.
2) Character needs to go a little faster. If you try to get everything, you fall behind very quickly.
Very cool game, though. Obviously reminds me of Tower of Greed, which had me hopelessly addicted for weeks. I hope you work a bit on the game play and give us a good second version.
