The demo doesn't launch the game at all. I get to see the menu w/options etc., but when I try to play I get a black screen. I'm on a 2012 MacBook Air w/Intel Graphics 4000 and the store says I meet all min. requirements. Bummer. Have to see if I can figure out how to contact the developer...

I put 2 stars because I can't say I hate it if I can't play it!
