awful
just awful. people don't want a cheat to get passed levels, they want a game that's playable. this game is not. i got to the third level and tried and tried and tried, but could never even jump up to the first ledge. the edges are never clearly defined. sometimes i would be right on the foremost box image, and sometimes i would be 10 pixels out on the "perspective" box. that is really bad, since i never knew how much ledge i had left to roll towards, or where i should aim for on the next ledge. really bad. i give this a score of awful.
and i would like to reiterate that instead of giving passwords, you should try to fix your game. which has some potential, but is sorely lacking.
