"The fight with Asgore, he clearly destroys the Mercy button. Hell, Flowey himself even introduces the basic battle mechanics as a real thing, with Toriel expounding upon them later! There is literally nothing that says the battle interface and HUD aren't real in the world of Undertale with these three instances, and even PAPYRUS of all characters adding onto it with the basic explanation of the Blue Mode."

The fight button was a metaphore. Flowey only introduced our soul and his pellets. Both of which I do believe are canon. Same with the blue mode, just a modification of our soul. Any other examples of yours that would prove that the world of Undertale is canonically a game, while the characters are for SOME unknown reason absolutely oblivous to such fact?
