Sorry, but that is simply false. You can see the rules
here, scroll down to "Prefix Definitions".
The Abandoned-Tag is applied, once a game has been effectively abandoned for three months. That means: No updates AND no news, either on here or the developers Patreon, Subscribestar, own website, etc.
All the Devs have to do is to swing by here and tag the game as "On Hold", sidelining it for however long they want. But this Dev, instead, chose to go completely silent on ALL Platforms the Mods could check. His twitter hadn't talked about the game in three months, and even that sounded like he's only referencing an earlier broken promise. His own Website mentions a Developement-Pause from two years ago, but doesn't mention anything about it being on Hold right now. And IF these posts about a Scene-Poll on his Patreon talk about this being worked on again, it's hidden behind the paywall.
So, neither is this the mods fault, nor do "we all know it isn't abandoned". Because we don't. I certainly can't see ANY public statement about his progress regarding 0.07 or his intent to even start working on it. IMHO, the Abandoned-Tag is rightly earned.
