The game loads. It looks like the menu system has the in game graphics running, and they run perfectly fine.
Problem is, keyboard doesn't seem to work, and neither does the mouse. There is no response from the keys on the main menu, and the mouse disappears when on the game window. May be the lua mapping that's not compatible, but that's not even a guess, as I don't know the first thing about this stuff.
But this does look promising. I'm sure there's a way. Going by the WTF video by Total Biscuit that highlights this game, it doesn't appear to use an emulated cursor:

Fingers crossed, I guess.
