Thanks for all the replies...
Your right, it is quite tricky, it seems to be a little less responsive on the PC than on the iPhone. Makes it trickier. Having said that, the more you play it the better you get. Attached is a screen print of our top 10 on the leaderboard, people are achieving scores well into the thousands (I'm on there to ha!).
@Conjured Entertainment, slowing the box down is definately a good idea. This was something we wanted to do but the previous SDK made it almost impossible. I'm looking forward to enhancing this game with AppGameKit!
Do you know if its possible to alter the FPS in game? Would be easy to try it out, but I'm at work so can't test it... I was thinkg that we could simply use SetSyncRate to increase/decrease the speed (or does this only work at start up?).
Again, thanks for all the comments.
