So by limited, you literally mean you can run the game, mess around with the ragdoll physics, and paint on the textures of the girls. I am aware the game just released and you want to encourage support, but for the actual amount of content free players have you might as well just make us pay for it.
Suggestion: give the free players more than just 2 dolls they can whack around and actually let them try at least 1 toy. Also a tutorial that is more than text on a wall would be great. Also a final suggestion, if you are going to have a void the characters can fall into, a respawn mechanic would be helpful.
Please keep working on this! I am excited to see where it goes but maybe make a less strict pay-wall if you plan on it being free at all.
