First, let me say this game rocks!!!
But I have to say that the choppy sound I get on my Sony Clié NX70 is a bit annoying especially since older PALMOS4 models don't have such problems. If you could fix that on a later version, it would be appreciated by a lot of first day customers like me.
Also, I thing there should be a menu or home icon on screen all the time during the game. The menu icon disappears during cinematic scenes which makes it impossible to quit the game. I think one should be able to quit a program at anytime, if only to avoid having your boss seeing you play WFI during office hours.
And finally, I too would like to have the possibility to play in landscape mode on my NX. Shouldn't be too hard to implement since it already exists on the PPC and UX versions.
