Just downloaded and am really looking forward to playing this. The only thing is that I can't get any of the "back" buttons to work. Right now z is mapped to "A" and right shift is mapped to "Select" by default, which should let me back out of the options menu or unselect a unit, but neither seem to be working. I tried remapping a few different keys to both and redownloading from the main site, but nothing seems to have worked. I haven't seen any posts about this either, so I'm not sure if this is a bug or I just keep getting a bad download or what.
