First of all, thanks a lot for the comment. It made me really happy to see that you enjoyed the game :)
I'm a huge fan of psychological thrill including trippy, weird, odd, surreal and abstract stuff. Also fascinated by such things like liminal space complex easter eggs. Those things will always find a way in my games (if it fits)
The person (Brackeys) behind the door was just a little easter egg. He is the origin host of the jam.
Speaking of this. The game was created in one week for a game jam. It was always in my mind to keep developing the project. However, I would do a completely new but similar game. I have a lot of ideas and write them down, but no motivation to start currently.
As soon as I can show something, you will hear about it :)
