@local - thanks for the input. We are actually thinking about doing a mobile version of this game, though we will not limit it to two button.... we are toying with a swipe control. You never know what you are going to come up with when you do these things, and the whole get fat for mass/get thin for jumping is a mechanic we are enjoying working with. I wish we had more time to do more levels that incorporated swinging through walls, but frankly we had a ton of issues getting the collisions to work right, but still have some way to go. A doughnut should not stop a swinging fat guy...
