Started years ago with couple high level ($20) tiers on Patreon. As the quality of games improved, I switched to about dozen games at $5 to $10 level. There are so many good games on this site so I tried to shuffle my pledges, mostly to new devs that were making less money. As the games became bigger, monthly updates turned to bi-monthly, then every 3, 6 and for some games even a year. Some devs delivered but I also got a feeling that some updates didn't warrant $50+ in monthly donations which is basically the price of AAA game.
So I finally switched to a per update model, mostly via Buy Me a Coffee site. I would usually drop $5-$20, and if update was especially good $30. This eliminated frustrations with "milking", short or low quality updates or long waits.
This is a pirate site but I believe that everyone shout contribute in some way. If possible financially, even couple bucks once in a while would help considering number of visitors on this site. If not, please be respectful to devs (after all, you're getting the game for free so doesn't matter how long it took) and especially to other posters. Some conversations on this site turned quite toxic even resorting to ad hominem attacks.
With that being said, I think that Artemis is probably top 10 game on this site with talented and productive dev, and that update will be well worth the wait.
