The IP is just not that popular. I JUST recently played the first one because the second game is coming out soon.
IMO if the game was made in 2023, they would've taken out a lot of the violence + sex. PC culture is not going to want a game where The Little Mermaid is a stripper at a strip club.
If you search for rule34 content, you will see there's not that much for the IP in general.
My hope is with the release of game 2, it'll become popular. But Pudding n Pie will probably be gone in game 2, imo.
