"If I voluntarily financially support something I cannot express negative feelings about it" lolThey don't have to give you anything. They could choose to reward contributors with artwork, in-game credits, the ability to vote in polls, whatever they want. It doesn't have to be early access. It doesn't have to be anything. You aren't buying anything, you are saying that you like the content, recognize the artist is creating that content for free, and choose to donate so that they can continue to create free content.
We are supporters, not customers.
I should add that if you didn't like the update, you are free to complain. It is a human right to say when you don't like something. However, you don't get to use your donator status to do so.
If you read my original post, I didn't attempt to leverage "donator" status as cause for outrage. I said I was dissapointed by the amount of content in the latest update. Anything past that is you seething that I expressed a negative opinion. I like angry furs work and the game, I was simply hoping for more.
