Itch.io is down...again... (Patreon)

You can play the free web version on Newgrounds, and it runs reasonably well over there. Of course, with Itch down, there's no way to retrieve your game saves unless you've already used the "save to disk" feature (which I do recommend doing periodically).

As far as the silver, gold, and windows versions, I'm not sure what exactly I want to do. I am very dependent on Itch not just for hosting the game on the web, but also for handling the distribution to patrons. It's something I'll have to think about, as Itch has been getting less and less reliable. It's gone down more times in the last few months than in the last several years prior to that...

Most other storefronts like GoG and Steam either lack good Patreon integration, aren't really ideal for ongoing development, or both.
