I raised my eyebrows how the "How to Play" menu doesn't actually tell you what is expected of you in the game, but it is pretty straightforward. Though your health level looking like some random number generator confused me, and I thought for a while that it is about timing, and you can cover more distance if you are fast enough. Once I've got everything though I didn't put it down for a while.
I hate sokoban games, and I still played 11 levels of this, because it got me curious, and the investment was relatively little (or so it seemed). So I think that says there is potential in it.
