I have issues where sometimes walls that require switches to remove don't show correctly in replays. Such as in Rapture when you hit the switches to remove a wall for x seconds, in the replay it never shows it being removed and meat boy just goes through the wall. Actually, I can't even think of a single replay where it has actually worked correctly.
Since buttons, keys, and enemies that follow Meat Boy around aren't all shown at once, it would be much easier to just show the level as it is without those things happening. Instead of clutter everywhere.
It's not just you.
