I'd normally avoid demos because they're often only good for short few minute playthroughs, generally taking longer to download than to experience fully, and True Facials is certainly one of those games. This is a review for the "TrueFacials_Demo_v0.27b" version, so things may improve over time.
All this felt like was a tech demo to show off cum effects. Models, sounds, environments and perhaps more are taken from other works, such as Overwatch or Bioshock Infinite. You'd perhaps think the cum effects would be pretty impressive if they appeared to be the sole focus of the project, but they don't seem all that much better than some SFM/Blender works I've seen, and compared to some are actually worse. It's too watery, lacks any definition and drips down like something a bird would release.
One omitted feature, which baffles me, is the ability to change the consistency or volume of what's fired each time. You have to build up a single spot if you want something that looks like more than a dribble, and the amount that leaks down only really seems to increase how white it is with more sprayed on top, rather than getting thicker in a more 3D sense. Where are the globs? The thick ropes? If it's going to be the main feature it needs to be a lot more fleshed out before just polling for new girls to add.
An additional gripe I have is with the controls; they're just not intuitive enough. The cock can get stuck focusing on a point of the body very easily, and the camera doesn't move in a way you'd expect, so expect to look at the control descriptions very frequently in the three or so minutes you'll toy around with it before it either bores you or crashes. (That's not a jab, it really did crash when I closed it a second time.)
Patreon stuff aside, this is just a bad "game". The one unique selling point, the facials, are completely unimpressive with physics and effects that are outshone easily at best and are just laughable at worst. If you want content with the characters, like blowjobs or something along those lines, check if any new content was released by your favorite SFM/Blender artists, you won't find anything worthwhile here for now. This needs a lot more work before being more than a three minute curio.
