I was practicing a speedrun of this game, and on the second level, I went up a staircase, and clipped through the floor. i then proceeded to clip into the staircase and get stuck. Then I clipped through the floor to the start of the level. Am I alone here? This was really funny and I wish I recorded it.

It is possible to clip through objects in the game. It has happened to me a couple times as well. I don't exactly know what causes it though? From my experience, it is most likely to occur when switching tabs.
