Even though I am aware how this will look and some people will jump on me for this, I just can't help myself..... which one is it? Are you a Patreon member to support the devs, or are you directly paying the devs to work on their game? Because those two arguments can't be in the same slot and still work.
Paying here on Itch is buying the game, being a Patreon is supporting the devs and getting the game. Support. SUPPORT. It is entirely up to you what you do with your subscriptions, obviously, but let's not pretend that the devs works for us. They are providing us something through their own work, and we pay for it if we want, no scamming involved.
Also, I wish people had better arguments for their issues with the development than "scam", "I pay these people" and "too slow".
EDIT: And like 5 minutes of reading, just here on Itch, will tell you, you don't need to pay a cent for this game. The Public version exists you know, and our own patience(or lack thereof) to wait for each new Public version is our own problem, not the devs.
