Hi T-Virus, thank you for supporting us!
This is what we wrote under the download of the alpha preview:
This preview shows you how the sex scenes will work. We will upload a proper demo soon. Hold your left mouse button and drag the mouse to let the sex happen. Middle and right mouse button to navigate camera. ESC for menu and graphics options. Orgasms are not implemented in that preview.
Hope that helps.
I've accidentally created unicorn vampire action when I wanted to make an evasion effect for Kalyskah. It looked so funny that I've had to share it with you!
