So basically while Eps is skating, if he enters a door while still skating, he'll continue sliding past the door before disappearing. This only works if he enters the door before or at the middle point of the door while skating with the Shears Legs.

I'm not sure if that's intentional, but I found it weird if he were to enter a room while a whole door's length away from the actual door.

This may or may not be a nitpick.
