Huh, I wonder if this can be exploited somehow. I don't really see how it could.

Mario will "stick" to any platform sprites while running up walls via a purple triangle, slowing him down to the speed of the platform until it passes by. One notable use of this is that it even applies to the animation at the end of a wall where Mario reorients himself, but his horizontal speed will remain unaffected, which can cause him to clip into the tiles in the next column over. It should be noted that this works with the solid platform sprites as well, but only if Mario enters at a position where he doesn't get warped out of it
That way ^
