The maker did it themselves. They use a very close copy of the minecraft layout. To say it is only inspired by "Lovecraftian Horror" Is just disingenuous at best.
there is nothing wrong about beingg inspired by a game, Notch admitted himself to be inspired by dwarven fortress. But people shouldn't just act like something they make, especialy when using their vast knowledge in modding Minecraft, isn't based on minecraft.
It has a lot of features base game for sure, but a lot of those features literally are minecraft with mods. A lot of other features and gameplay aspects are not. And that is good. This game definitely has its own seperate soul. But again, it's disingenuous to act like this isn't a clone of minecraft at its core. because it kinda is a clone at its heart. And that is Fine. because that is LITERALLY why this game was made. it's a minecraftlike, and the makers should own it.
And people shoudln't act like it is something seperate entirely
11/10 game
7/10 honesty
Tldr, they could do better
