The 'newest' build usually hits at the same time as the itch.io page, but only for the people who pay for the most current build, which is $5 USD at the highest minimum on the itch.io page and the same price monthly on Patreon. Patreons get access to most of Isolated's other content and the discord, like WIP art, comics, that kind of stuff. Patreon is better if you want to see more than just FNaFSO content and don't care about a monthly fee, but if you are just interested in FNaFSO, then it is better just to pay the $5 once and get access to the most recent build on the itch.io page.
Sorry if I came off as some arrogant asshole, I don't know how I could have worded that in a way that came off better.
