Tried out your demo and I figured i'd give some feedback, even though its just a quick demo.
1. Have a basic gameplay loop in your demo, just moving around will leave people feeling slightly cheated since theres around 10 seconds of content.
Add something basic like a fetch quest. "Get the lollipops and then talk to the girl".
2. I like the models, they're cartoony without being silly. If you stick to that 3D style then I'll more than likely look up your game in the future when its a bit further along.
3. Look into creating some sort of "Drag camera with mouse" option, its a bit cluckly to rotate the camera. Q and E would also suffice, again, I know its a demo, but its just one of those "quality of life" things.
4. Maybe add the option to undress in the inventory instead of esc? I didnt notice I could undress until I pressed Escape to try and see if there were some sort of information about the game there, seeing as 400mb is quite large for what is on display. Before that I just X'ed out in the top right.
Good luck with your development, I suggest moving over to Unity or Unreal Engine with your game. I havent developed in Unreal, but I have developed in Unity, and just the fact that you can export the game to Mac, Windows and other platforms when you publish your game is a huge time saver since you'll likely have a Mac user or two wanting to play the game.
