Honestly... I don't mind crappy art. Curiously enough, I prefer bad art over real porn (as in still images and 4 second videos/GIFs). If I wanted to watch real porn, I'd go to Pornhub or any of the other porn videos hosting sites.
Hell, I'd say this... I prefer crappy 2D art over uncanny valley 3D models, you know, the default ones from DAZ. Pair them up with bad lightning and holy shit, that's stuff for nightmares! Wretched and botched facial expressions kill it for me rather than bad body proportions. Don't get me wrong, bad anatomy is still weird af but it's more bearable than twisted uncanny valley faces, at least for me.
I'm hoping the Patreon page is not a quick cash grab (despite the looks of the game) and the dev eventually hires someone to do proper art as to not scare people away from a project. This reminds me to the game
Absolute Power Corruption, where the dev had his original art hand-drawn by himself and later on hired an artist that made it look better, so here's hoping that scenario applies here as well.
