Are you new here? 1 and a half years just means Hiddenwall's missed about 1 to 2 updates. Kingsguard was getting about 1 update like every 10 months. Missing for a year and a half due to uni and IRL stuff isn't exactly outlandish in light of how updates had come out before.
Until there's a game update it is dead. I will also note that despite what he posted etc. It did not stop him from taking people's money on patreon and producing nothing for almost 2 years. Worse than blackgate.
You know people WILLINGLY give money on patreon? I agree i would have liked an announcement, but i would have still continued my subscription. Personal preference, if you don't want to give money then don't.
