The game is actively still in development, but Killer works on two games alternating. Right now it's in the development phase of My New Memories and a beta for the patrons is out. The second one is also coming along. I played the first beta, so yes I know for a fact that it is still in development. If you would actually read the Updates on Patreon (for which you don't even need to be a patron to read...) you would know that already though.
