I'm having some problems (that fortunately don't get in the way of actually enjoying the game) in that some of the controls don't seem to be working properly? For some reason pressing "up" doesn't actually do anything, and in the Config menu, I can only increment, not decrement sound values. I'm not sure what causes this, but I now can't reduce the volume of the sounds or the music, and navigating the menu in only 1 direction is a bit annoying.

Anyone else with this?
