Wow! That's actually the last level that I've made, didn't think anyone would be remotely interested enough to take it that far. Thank you for playing!
The trick of that level is to stop the blob from moving while keeping your steps in tact, then push yourself forward. The amount of steps given is exactly the distance from start to exit.
Well, if you don't mind me spoiling it:
First you waste a couple of steps to get the blob out of the way, push the boulder to block it, then rewind to get your steps back. Next set yourself up to push yourself forward by standing behind the boulder, walk around the boulder and push it back, then rewind to push yourself forward. Rest is the same as the previous levels.
