It is NOT time yet. If a FULL YEAR goes by without an update. Then we can start thinking if it's abandoned. It's "only" been 5 months or so. It is getting a bit worrisome but I am pretty sure he has gone this long without updating before.
The forum has specific rules on when the Abandoned tag applies, not whatever time you (or any other user) thinks the tag is justifiable. According to the
rules stated here :
- Prefixes
--- Abandoned
------ "After 3 months of inactivity from the developer's public creator/crowdfunding accounts (Patreon, SS, etc),"
Same thread but a
few posts bellow:
--- "The game has been abandoned (confirmed by the dev) or the developer hasn't
been heard from posted anything related to the game for at least 3 months."
The last post from the dev on both Patreon and SubStar was in September, and their Twitter account is currently suspended. You specifically stated it has been 5 months, which means the other user is right and this game should be tagged as "abandoned", at least until the dev re-establishes contact or posts anything new.
