He didnt really abandon ANLIS, and he had a good reason to switch projects. ANLIS is way too big for a part time, solo dev. Also his games are free? If you think his tactic is to money grab by switching projects just dont support him, you still get the game anyway.
I agree though I think he definitly should be communicating more, ultimatly what I hope happens is he finishes BRH (shouldnt take long as it isnt planned to be as big as ANLIS, its in his scope.) And hopefully he gets enough money and support from that game to be able to go back to ANLIS with more tools to get it done faster. I am really hoping he posts more on his patreon so I can actually have a reason to subscribe and support him.
