Really fun game! the concept really reminded me of "There Is No Game" but you did take it to different genre, with different concepts
I liked how the "It is not real" was a part of the story, everything was not real and the cool unintended bugs added a lot aswell
During the playthrough I was really hoping for a cool twist, for example: what if you had the power to crash some parts of the room by doing things that you shouldn't, to then reveal secrets
Also, I think that more levels where the solution is not the obvious solution would really add a lot to your game, just like how you did with the key puzzle.
You could've gone a step further and used the pause menu to stop the settings button from running away so it'll be easier for you to catch it.
Anyways, great entry, has a lot of potential!
