Got to say: this is a jewel in the making. Lots of rough edges here and there, but it has, imo, huge potential.
Most of the 3d characters are pleasant (to my eyes, at least) to look at, but the author really, really should spend a little time researching and learning rendering techniques, especially concerning proper lightning. By basically using better lighting this game would have a huge improvement, graphics wise.
If anything, just rendering your character's assets (not the whole scenes) in something like Keyshot, which can be learned rather quickly (it's quite possible to do good renders in it with a day or two studying it) would bring a huge jump in quality, for very little effort.
Avoid darker scenes (it's one of the biggest tricks guys like DS, from Big Brother, do). Rendering dark scenes is very, very hard (even major game developers struggles with it), so go with as much light as possible when rendering.
I can't tell for sure, but some of the characters' skin textures looked a bit subpar, imo. This should be a fairly easy fix to do, so perhaps do consider using better skin textures.
Some Photoshop on the static scenes would go a long way too. It's another one of the secrets other Patreon game developers do.
On the plus side, I really loved the amount of work and detail you gave to the BGs. It's something a lot of patreon creators gives little attention (some of which are even well know for their rendering skills). Well done!
I do like the overall story, and personally loved the humor touch in it. If the author can improve the graphics just a tad, and deliver constantly, I can easily see myself as a future backer. As of now, I'll just follow this with great interest.
