Its been almost a week and my game is still stuck processing, I received no reply from itch.io support.
At this point I have already moved my game to Steam, it sucks that itch.io support is so bad, I'm actually working on a large multiplayer RPG with a decent follower base, but it seems projects like mine can't rely on itch.io as a reliable platform.
Moving forward I would only recommend this website to people looking to make really small games with no updates, any large project that requires constant updates (like mine) is at risk of suddenly not being able to upload any more patches and get 0 support from itch.io staff.
