I took a tasting of version v0.2.0 and here's a summary of what I played. Press "I" to open up a control guide. Press "Q" on the keyboard launches options for character models (Andrada, Destiny, Judy, Lucia, Melonie and Roxanne) 6 hairstyles and hair options from color, intensity, brightness and length. For this I chose Lucia rocking a Zita hairstyle. In this open room, there are 3 areas for sexual interaction; the bed, vanity table and sofa. The model's movement is best described as action game; from walking, jogging, full sprint, stationary crouch, walking crouch, stationary jump, forward jump and backward jump whilst facing forwards. There's even some climbing, especially the back wall of the vanity table. Interestingly, when using the mouse to rotate to see the model from the front, she'll look both ways before turning around, back facing the camera.
For the sex scenes, speed is adjustable and so is the camera by holding down either left or right mouse button and manually move the camera around. There are a total of 6 sex scenes and arguably my current favourite is A2 from the vanity table.
I like how the model has the presence of mind to protect the back of her head; to lessen the chance of getting a concussion; especially when being pounded out by Dirk Gray Man.
By accident, my true favourite from Project GWN v0.2.0 is ragdoll. Pressing "R" on the keyboard causes the model to fall to the ground in various ways. You could full sprint to the vanity table wall, forward jump, press R and she'll clip the top edge of the wall for a somersault fall. In effect, you can create stunts similar to those found in the T.V series "Jackass". All I want to see is a female model say: "Hi I'm Lucia Knoxville, welcome to Jackass".
As for criticisms, the only sound effects in the version are foot steps. However, the foot step sounds belong with boots rather than bare feet. There are no facial expressions from the models during intercourse, so it's impossible to tell if the models are having a good time.
For a very early version, this might have potential. At this early stage, I wouldn't worry about adding voice sounds just yet; unless the developer wants to add voice sounds as a place holder.
