This is really neat. I think I encountered an audio bug on restarting though. It seems like another instance of the music would play. I played a lot of Lemmings when I was younger and this reminded me of that. The players are a little fast and a little random, but that's kind of what we expect of players. You said you had some time constraints added by real life. I think if you had the full week to yourself it would have been amazing. My only complaint is having to get the platforms pixel perfect. That could be frustrating at times. Keep adding on, I think lots of people would really enjoy this.
