hi! i hope it's the right place for this, i really want to try the demo and the game starts normally but the screen stays black. i hear the music and the setting choices sound effect when i run my mouse over it but i can't see a thing. i tried to reinstall it and reextract it but that didn't change a thing. can you help me figure out what's going on?

Hi! What operating system are you running it on and what zip file have you downloaded? 

When you open the game, try pressing the Shift + G combination to open the graphics menu and try switching between different settings in the “renderer” tab of the menu (you have to restart the game to apply them). 

If this does not work, try updating your OS or/and your graphic drivers. Let me know if this helps!
