It starts off as a nice, kind of easy little puzzle game, with the nice funny theme of the lab rat collecting food. It gets different and harder when you get to the "broken" level and you get this boss. The laser beam doesn't seem to follow any pattern, instead always trying to nail you right where you are, and that makes it very tricky. The graphics and the sound are great, so it's enjoyable to play.
I'd like to invite your game to our contest, the Game Development World Championship!
