Thanks for the tip on the rotate app. That will come in handy for other things, but unfortunately its not the issue with this game.

Its kind of hard to explain unless you've tried to play it on the tablet. The game is made to be played with the tablet oriented vertically and you tilt the tablet from side to side to move the character. Unfortunately, when you hold the Arnova vertically, the game acts as if you are holding it horizontally so the movement is incorrect. When you hold it horizontally the screen orientation stays vertical and does not rotate, but the game acts as if you are holding it vertically. At that point the movement is correct but you're trying to play it while looking at it sideways, so obviously it doesn't work very well.

I was hoping there might be a solution since it is a relatively popular game, but it sounds like it might just be one of those things that doesn't work on this tablet.
