I wasn't able to start playing -- the game seemed to not know how to handle my 4:3 aspect ratio monitor, and the menus were layered in a way that covered up the level select. (Guess I found an edge case for you!)
I wasn't able to start playing either, with a three-monitor setup and no way of finding any controls to start a game. The top and bottom of the game were missing so couldn't see any menus. Would love to play this with my 3-year old!
