F95Zone applies the "abandoned" tag to games that have gone 18 months without a new release. This doesn't mean that the creator has announced that they've given up on the game, just that at some point it stops being reasonable to expect another release, and here the arbitrary line is drawn there.
The dev is reportedly still saying they plan a release in the next few months (they were predicting a release this month until Patreon shut them down a month or two back), with at least Subscribestar and Steam releases planned. Some posters have expressed scepticism - I don't know the developer well enough to say either way.
