I'll just copy paste my previous anwser to this because people are just very inconsiderate:
Lmao some people see a low poly fps and immediately assume it's a Karlson clone. Probably the only thing that was directly inspired from Dani's game is the floating gun without a hand model, but that was done way before Karlson
Please don't accuse other people of reskinning other games if you have no idea how games are made in the first place. Thank you
