I quite enjoyed the game! Though I've played others like it, it was rather good. Graphics are nice and cartoony, simplistic... And the controls and gameplay are fun. My biggest complaint, however, was the sheer amount of airplanes in the upper atmosphere. I ended up having multiple walls of airplanes that I couldn't maneuver around, forcing me to hit them and either lose momentum or start into a nosedive. I really, really wish there'd been some sort of inertial dampener upgrade, but alas. In any case, a fun game, and a great time waster.
