You are right on several points, except of the part "[...] all but vanished". The game is the greatest single-man project I ever heard of and has still lots of fans - they cavort on Discord, not here. You should take a look on Discord server before pass judgement. I agree, Komisari seems to be very slow in development and comes with lots of delays, but on the other hand his update v0.1.2.2 from May 2023 brought very much great improvements (graphic and features).
Komisari probably tries to make the 100% perfect H game. Like everything else in life its not reachable, but he is very close to it! Though its too time consuming, that cannot be denied...
