From what I can understand the game has been fully rebuilt from the ground up. For what reason? I can't say. maybe the dev coded himself into a corner and couldn't continue since they are still a beginner from what I can tell.
Apparently he is planning to have update cycles of 1-2 months and the update will focus on as per his fanbox:
Arm and leg options
- Limited hanging simulation (escape mode)
- Indoor room map and park map
- Suffocation and strangulation simulation (custom mode, escape mode)
- Added animations and sounds
after which he will work on the "underwater" update.
At this point nothing else left than to wait and see.
