sorry for the double post, but the game needs sound, something that doesn't get annoying though... or if not sound efects, then music, possibly changeable.
I like games with badges =D and AWARDS!!! =D =D =D =D 4/5 because I'm picky with 5s =D! And no, I am not on anything, and have not been for the last 5 minutes (that was just for laughs!!!)
It's nice, I'm giving it a 4/5 nice concept. You should include a map editor and make more levels of the campaign, although I'm not sure what more configuration can be done...
