Ravenous Games, best known for the League of Evil series has a reputation for delivering precise platforming experiences to the iPhone. This week they're releasing Gravity Duck, whose main control method to get around each level is to change gravity to fly through hazards. It looks like an extension of the gameplay present in VVVVVV. Have a look at the trailer!
I'll be looking forward to this one, and as long as it controls smoothly, i foresee having a lot of fun with the title.
