officially it is until dev gets back to it (if does).
The game is not
officially abandoned...
Officially means when the dev says "Hey! I'm quitting! Go away now!" Here's not the Supreme Soviet to decide what's abandoned or not... Of course, they can decide for themselves and label the games the way it pleases them because it's their site, but it doesn't mean shit until the dev says so or there's some unambiguous sign, like the shutting of its Patreon page.
there is/was 1 where dev got 1 dollar per month aka 365 bucks per year before patreon cut etc.
Well... They're free to leave... I don't think that's the case here. The dev of this game doesn't get a lot of support (only 111 paying members), so, as the dev already stated on his Patreon page, it's a hobby project he does in his free time. It has happened before -- game was labeled "abandoned" here, but the game resumed, there were a few updates, and the announcement the game is in its finishing stages. I'm saying all this because, again, I don't think this game was really abandoned, but, even if it were the case -- here and in any other game Patreon page --, if its patrons are too dumb to not press the "leave" button, they deserve to be ripped off...
