Ah, It's paid now, ain't no surprise here. Guess I should find a different title to play. I'm not a guy that just plays shits for free, I can buy the game. Cuz 10$ ain't that much. But the problem here is you didn't say that game gon turn into a paid one, you just change it out of the blue. Christ, man.
Admittedly, I'd have preferred notifications here as well, but I also understand how many different things you've got to juggle in the world of game development. Hoping it'll be a good learning moment - I love what you've made so far and at least for me, this move isn't a deal breaker. But, you had posted it on your patreon (public) what you were planning, I had only read it yesterday so I wasn't (knee jerk) surprised.
