Oh thats good too hear! I hope he is doing well and will return to this game at some point. It has a lot of potential for sure. I will edit my post a bit in this case.
Are you able to reach him on reddit perhaps and ask?
I really hope this is not the case, and I know this might even be offensive to some, but it is possible that Adam is dealing with severe mental health issues. As I said, I truly hope this man is doing well and is just on a longer break. This game is awesome, but if you have played his other game, Adam - Lost Memories, you will find that Adam had a very troubled past. Take this with a grain of salt, of course, as it might have been written solely to set the tone for the game. However, I doubt he stands to gain much from lying about such a topic. Here's a copy-paste from the Steam page of that game:
I created this story-driven psychological horror game based on my personal experiences with child abuse.
Fear in real life is not from zombies that want to eat your brain, or the ghost that came back from the afterlife to open your fridge while you slept.
True fear is when you cry in the corner of your small room for some food and water. When you are constantly shamed and humiliated for years and you can't see the end of it.
I want you to feel this type of terror because this is what child abuse really is, and I think more people should talk about it.
This is not a walking simulator, and this game does not rely on jump scares. You play as a mentally ill person who suffers from panic disorders.
You play as me..."
As you can see, our game developer here has not had it easy, assuming this is true. So please, be considerate in your comments and send your prayers and best wishes to this man in the hopes that we see him return to developing this amazing game.
