you need to read dev's post on his patreon and don't lie about it
He was more interesting in improving his skills that making a game. He moved from daz to blender because of possible optimization, then he started rework (no one asked about this as well as about migration to blender)
then dev broke his arm and can't make renders, he coded new in-game phone (no one asked about it as well), people still supported him, after that he just disappeared
this is the whole story
