I would write down what I don’t like about it, but the game’s creator doesn’t care.Why does it say it’s free, but it asks you to go to Patreon?
I do care about feedback. And the full game is free, with all mechanics accessible; the only thing locked is additional characters. For me, this is a good balance. You have a chance to test the game, and if you like it, then support it by trying out the other characters.
Do you have a list of the characters available? That might help people, if they know whether there's a character they want before they have to give money to find out they don't like any of them.
