Very definitely done by a different artist, but also very definitely unsubtly inspired by the success of the other one lol
IDK man, I feel like we're seeing a bunch of games from "very different artists"
Still, the style of this game is far from the MO of the "Shitty unity society".
Usually their games are 3D go from point B to point Z. But who knows, they could very well be behind this game as well. Maybe they've haven't had enough corrupting unity and renpy, they also want to corrput the RPG market.
For now the game is practically non existent so it's irrelevant anyways. If we see a trend of games that seem to be kinda like this one we'll know for sure.
