It's a shoot-'em-up game. OK, it's not a regular escape game. Those little cute dudes at the bottom need to get across the screen before the grey dingbats hit them. Fortunately, you can explode dingbats with a mouseclick, boomshine-style!
Mouse for exploding. Good luck.

Note to admins/mods:We have two games titled, "The Great Escape" and this isn't either one of these, it's a new one.
