The idea behind this game is brilliant, and it's very well executed. However it's very annoying when the past selves' movement isn't saved correctly, I gave it a 4/5 for that reason.
@furball it's not a lie actually. I know it sounds ridiculous, but it's true. Check the highscore table, it says 49 levels completed (obviously I could have cheated to get that score on the highscore, but I'm not quite that low)
While the game's concept is good, the completely broken AI ruins it. Having them stand still would have been much better than the ridiculously movement choices they make now. 2/5
