The game-style is really good and the art is amazing too! Music was a bit too loopy, but that didn't bother me. I got addicted really early! (doesn't happen that often).
I first began to play this game for the medals, but now I replay the levels just for fun! Even got the 'flawless infiltration' medal and it was really fun, not annoying as some games are!
Overall - Thank you for this, this is certainly one of my favorite flash games now!
