The free app of the week on iTunes is Le Vamp. It’s an endless runner. The endless runner genre just means your character runs on its own. It’s your job to jump, duck, etc. to avoid obstacles. The idea is the same throughout these sorts of games, (think Tiny Wings), but the game itself will have a different setting or action set.
The game is free right now. We don’t know what it normally costs, but that doesn’t matter because you don’t have to pay for it right now.
You can check it out on the App Store:
