One of those ever rarer games that make me click on them immediately. I like this idea, quite a lot. The execution is simple, but pretty good. Both the controls and the level designs aren't too frustrating (version 1.03), but offer enough challenge to almost make one give up before completion. The weirdest part I ran into was on level 9, where it's hard to jump back up and not get stuck between the rock and the hard place. It could have used some more window dressing, like a proper victory screen that's more than a dry announcement, but overall a nice quick game.
