It would be very helpful if you could detail what you're having issues with. The game is still in early development and a lot of features are not fully implemented. Our focus so far is around the camera function and stealth. Please see the roadmap for upcoming features.

Can you tell me about the hardware you're using? What operating system you're trying to run the game on? Just to confirm, please make sure you're drivers are up to date. We recently had a lot of people talking about the game crashing and it was a driver related issue. This affected both linux and windows releases.
