I played the demo and I really liked what you had so far. I just wished I could have held down a button to dispense those doughnuts versus having to mash it, which was really uncomfortable for me. Also I would like to see the game get steam deck verified.
I think having the story revolve around the developer trying to continuously create bigger and more elaborate obstacles for the button would be the best way to go, with plenty of opportunities for mischief in the process as you're trying to get through them.
Another thing I would love to see is some Easter eggs like the companion cube from the portal games. Can't think of anything thing else at the moment, but I'll keep posting replies as they come to me.
Just under the article was a video about how they also banned music. With all these strict, bizarre rules, I wonder what you are allowed to do there besides stare at the wall.
