Good overall, very fun. The only complaint would be in the levels where you have to keep certain units from getting across. MMM2 has a LOT of explosions, many off screen, and sometimes these explosions cause enemy units to fly all the way across the screen and you to lose these levels because there is no chance to stop them. This is VERY frustrating as it's not you fault and there's very little you can do, but you lose the level nonetheless.
