For some reason, I can't play the game.
As soon as I press 'Play' it shows the name of the game, then goes blank. I can access the menu, but nothing else works (just a blank screen).
Can anyone help me?

What has to be done in game. Game works fine.

the mouse is way too sensible, and no settings to change that
wtf did these programmers smoked

the new portal game looking good :P
