AMAZING game... the only thing I find is that the money powerups give you too much in comparison to shooting planes. You can shoot down 50 planes, but if you get one moneybag you make more than the rest totalled up. Other than that amazing game.
Great game overall. The worst part I found is that once one alien gets behind you he goes on a rampage, and if you didn't focus any facing backwards he'll just go through the whole group leaving you with no one left. other than that great game
