Angry Birds wasn't enough for you, then you may want to try MiniSquadron, a 2D dogfighting game. The Minis version seems to be a direct port of the iOS original, including 8 worlds and 50 planes. Unfortunately, like all other Minis, there's no multiplayer, and no added content to make up for its omission.
MiniSquadron has been a fan favorite on iTunes since its debut, with an average four-star rating since release. Check out the trailer after the break.
