Downloaded and installed in iPhone 3G. (not try on iPad and iTouch.)
It crashed when first load. I think it caused by OpenFient.
It work "OK" in the second played.
Just like jumpbot, the playing instruction is good for the very first time play. If the player is played again, change the message to "Ready to Jump?" or something like that.
It run some lag at the first play. It work ok when I reboot the iPhone again.
I think the tweet score is not finished yet. It will return to the main screen.
Just hope it will reduce the use of memory. And it will run more smoothly.
Will try it on iTouch tonight.
