The dev is well known to take long, long, long breaks between story content to do side-content fluff, add new female characters, etc. He was nearing the end of Chapter 2 and took a 12+ month break to do side content... and the size of the updates have shrunk dramatically as well.Why you said that? Is clearly advancing I mean, is now in the Act 3
He stopped the 12+ months of side-content to do 2 updates which finished Chapter 2 and started Chapter 3, and then has gone back to doing filler content, side content, re-doing stuff, with small tidbits of the main story thrown in, etc... and that's been the past 3-4 months. So when will there be any actual real full progress with the story apart from tiny bits and pieces here and there that he's been doing... another 6? 12? months.
So when you have a dev known to spend months upon months remaking stuff, adding new systems, ignoring old content, ignoring main-story for side content and filler content... combined with such small updates.... are you really surprised ppl doubt the game will ever be finished, instead it'll just keep going on and on while the Dev milks his followers of their money.
