You should honestly calm down a bit. I can sympathize with being worried for a project to be abandoned without a word after months of silence, left in a limbo, i saw too many, but this is not the case. Really, you are talking as if you were in his mind, but you didn't even work on the game, know him personally and maybe aren't even in the discord.
He may or may not change his mind about his next projects being exclusive or not (this one is free after all, patrons are just a version ahead) and he isn't scamming anyone. Also, he had his delays from 0.1 to 0.2 too, but he did deliver, didn't he? And he was chill about replying when questioned about it, i assure you.
Free to not believe us, move on and keep an eye on this or not, your choice, but don't come say it's dead like it's a fact, thank you.
