I see... but what if he makes something like a patreon or something similar that can help? Since patreon is optional so it isn't forced meaning no one shouldn't be negative. But people still have an option to support and I'm sure a lot of people would like to support this him and the game. Another thing he can probably do is people can probably pay very cheap to get a version or two ahead (if he able to be ahead) but people are still able to play the game for free, it will just be two versions behind.
I mean.. he can ignore them really... They just have to wait and let the important things and main updates go first. Why focus on the very minor things than the more important things And I'm sure there is more people who want the game with care and focus on the main part of the game than a couple people who wants to add their fetishes into the game.
And isnt 300€ more than 1$? Why not listen to you then if he's to just listen to whoever is paying him? (I don't not mean anything rude at all, just curiosity)
