I've had a couple of other issues. 1: the camera pans too slowly, so that I can be almost off the screen before it'll show where I'm going. 2. I got stuck on a piece of rock. I had gone down to the bottom of the screen and the camera wasn't panning any further. Then it did pan as enemies came in, but the controls wouldn't let me move anywhere. Needs a bit more debugging!
However I love the music and the way the western theme has been carried through to the cursor and the HUD screens.
