its pretty good... sometimes it gets a little screw u just gotta get used to it... the accellerometer on this phone was mostly made for stuff like tilting it for the keyboard. Not too sensitive or accurate but it is definately playable.
Sometimes it wont react to my tilting it, but usually it works fairly well..
I've been trying to play EDGE since I found it on the Impression forums, and it certainly reacts to the accelerometer, but with mixed results. I have to tilt the phone at the oddest angles to get the cube to move, and the angles that I tilt don't seem to correspond logically with the cube's direction of movement. I have calibrated it multiple times as well as reinstalled, but always with the same results. Guess you lucked out the jtap.
Thanks for pac man Ago. Works fairly well, but SO HARD to play!
