I Really can image this like a very cool game that can be expended. One mechanic that I think that woul be awesome, would make sense and be great to resolve pratical problens would be something that says the bug X has been fixed. Like in the first roon, after you pass through the it would say in the corner: "Walls collision bug fixed". So you would no long need to try to pass trough any other wall after this. And you could like don't fix some bug, like G didn't notice, and the player would hnow that you can use it later. I really think this games could receive a inprovement and made it awsome. It could be like Stanley Parable, you trying to figure out the fourth wall secrets and mechanics, it woul be incrideble.
