I buyed the game some months ago, came to check the new update, but... I have to pay for it again??
Viewing post in Pure Onyx - Alpha Release June 2023 comments
Well, after contacting ITCH.IO support, this was their answer (for anyone interested):
"Hi, I have purchased this game on February 2023, now I got an email about an update for the game, but when I get to the site, it ask me to pay again, this time 8€. Do I have to pay every time the game updates or what? I dont understand."
So seeing @euromancer answers other topics but not people asking this, I just recommend posting a bad review at Trustpilot.com, so they take action, at least, into removing this kind of scams. This is not supporting indies, this is scam people making them think they are actually buying a "early access".
You didn't look hard enough. Also, the answer is right in the project's description.
See below:
Hey, thanks for your support :3. These releases are mirrors of our monthly Patreon/SubscribeStar releases, so they only receive critical updates. New monthly releases need to be purchased, just as our backers on Patreon/SubscribeStar would pledge for a new update. We largely provide our content on itch so people don't have to sub (and for people who can't use those sites).
Once the game is complete (and probably during the early access stage) it will be available for a single price.
