This doesn’t happen to be from Super Mario Bros. S, no?
Also I found a weird glitch in the Super Mario Maker S game, where sometimes ground and semisolid tiles won’t show when you play the level, but there’s still collision. You can also apparently clip inside of walls with a certain setup.
And you can also clip on top of a singular block near the right wall in W1-4 where the first Power Moon is, and from there you can’t get back down without being timed out, or exiting the level.
