are you even allowed to make this game paid like did you ask sam hogan because it's his game

technically there is nothing stopping them from doing because the only thing taken from sam hogan is the idea but the source code is original and was made for this project wich in that case gives the developpers full right to make the game paid (i'm not really good at law but it's probably something like that)
