I've finished the demo when I posted. :p (unless I miss something in VIP room, cannot seem to interact with the two named characters).
Had lots of fun, cannot really think of something to suggest. For other bugs, I think when spending the attribute points very often have the event picture "stuck in the blue scree." Characters can move but the screen block most views, have to turn off the game (the blue event page is shown at title screen as well)
