Unfortunatly the game does not work correctly on my computer, due
to the shaders you use.
At least I could play Blackjack, wich is a nice game by itself.

You should put the system requirements on your page too.
Also 177 MB is too big for a demo.
Try to use only one location/girl for the demo.

6 Minutes gameplay is also too short. try to extend this to 20 Mins or so.
