I really love the simplicity. The aesthetics -- both graphics and sound -- work really well together. The one-touch control and vertical nature would make this perfect for phones. You could touch it up, add a few more mechanics, and publish as is. My only complaint is I found myself a little bored with how slow the platforms were moving. I also would have liked a greater consequence for the "fake" platforms -- as it was, it was only just an incentive to get the jump right on the first try, which is what I would aim to do anyway. Very well done.
