Not sure if these are all bugs, but I know at least the first one is:
1. When in the game menu if you go to options and click Game, Graphics, or Sound, the text on the menu selections disappears. It flashes briefly before disappearing.
2. Alt Tabbing does not work when this game is in fullscreen mode.
3. Moving the mouse to the edge of the screen in a multi-monitor setup will cause the mouse to continue to the next screen.
4. There is no way to clear key bindings.
5. You can assign the same key to multiple actions.
