So i got my iPod Touch a week or so ago, and i have some games (flight control, fruit ninja, cut the rope, etc.) and i was looking for more suggestions? around the $0.99 would be great.

Angry Birds is necessary, and $.99.  Monster Mayhem is a good gesture based defense game, and free I think. 
 
The Angry Birds Halloween expansion isn't as huge as Angry Birds, but worth $.99 once you finish the first. 
 
Doodle Jump is ok, Mega Jump and Froggy Jump are two free knockoffs.
