hmm...
pros: very 'childlike' feel (annoying sfx, simple, easy), pretty fun, CUSTOM LEVELS - better levels than the built in ones are available
cons: repetitive levels (only 30 too), horrible level design - no innovation, levels are monotonous, horrible AI - screw up simple things like 'I'm above you, climb ladder'
good game, i like your thinking... but it's really sloppy, with things that need work.
