A short puzzlescript game about cleaning up after a monster and then trying to trap them so they can't make any more mess.

(personally I don't think the best choice was to keep level 7 in because trapping the monster is impossible but I left it in anyway because I felt it is kind of interesting before it gets too tedious. So I don't blame you if you don't like it :P)
