doesnt matter if he still active in discord or other social platform, majority of people will think it is a dead game/vn when they realized it is already more than 1 year without new chapter, and more than 5 months without any communication either in patreon or subscribestar or itch.io. and lot of people of that majority wont even touch it as to not be feel disappointed after playing it just to be left in a cliffhanger for who knows how long or even forever. it already lost its momentum and most people who know about this avn wont recommend it to anyone anymore and try to forget it. as it is tagged as "abandonned" for a reason.
as it lost its publicity and the dev lost it credibility (ghosting their patreon for months), the only way the dev can regain his credibility if only he can release a new chapter every 2 - 3 months constantly in the future which i have a very hard time to believe he can, judging at the state of the game and his patreon
