Here's the short answer:
Withdrawal availability. Patreon operates in more countries than Itch.io. We know this because someone donated to us via Itch.io - and we simply can’t withdraw that money. It’s just sitting there. And that’s the most critical issue.
Other reasons:
1) The platform’s popularity. A while back, we posted a banner asking for support via BuyMeACoffee.
Not a single donation. Zero. Meanwhile, Patreon is already performing quite well.
2) We’re not just game developers. We’re also artists. We have platforms on various websites where people already know what Patreon is (because they support other artists), but know nothing about Itch.io. By using Patreon, we can attract them as well - something we wouldn’t be able to do here. So yeah, gamers not our only target audience.
3) I’m not entirely sure about this one, but I think Patreon has lower fees?
4) Itch.io isn’t stable. More than once, I’ve wanted to share my game while chatting with people, but at that moment, Itch.io was down. And it was down for a long time - about 7 hours. As far as I know, that never happens with Patreon.
5) Itch.io imposes a shadow ban on games with 18+ content. As far as I know, unless you specifically search for our games by title, you won’t be able to find them.
