You could make a graphics option...like, on menu when player starts game, they see 3 options "Low End Device" Where it leads them to levels with LESS objects, and "High End Device" Which leads to the game where you added more objects. Would double the size of file but may be worth it.
Yeah. TYPE:RIDER is a cool game and if I'm remembering correctly, I think Apple Featured it. Possibly even on the top line. That may hurt your chances of your game getting Featured, but hopefully I'm wrong.
Wow, the game looks awesome. Interesting gameplay. It's the first paid game, I am going to download from the app store
Those left right arrows showing the player how to move, how did you get it to show up on game start only and not repeat
