Great but...
It was an exelent game but i found a couple of problems:
1:The last guy on hard is easier than the first guy on medium
2:On the guy with the biplanes and clouds, when you shoot the homing rocket it turns around and flys straight back at you and when it hits you, you fly off the map.
Overall its a great game.
BTW, i gave sound a 0 because i didnt have my speakers on XD
