Hey just baught your tool and I must say it is pretty good!
Have you ever considered to enhance it with some props like helmets (knight helmet or leather etc.) and other wearables (medival armor, futuristic clothes). Your great tool is limited to modern time.
Because that is exaclty what a lot of people (me included) would want for their hobby video games and nobody offers this on itch or the unity playstore. So if you could pull that one off, I would even do an extra video on my gamemaker tutorial channel (I try to give creators free cloud) and recomment you!
