Hi, wondering if you can specify for me the rules on any%. What does clipping through the exit door entail exactly? If I wanted to, couldn't I just clip through every door such as the section with all the blocks being pushed around, or the final door that wins you the game after clipping through? Just a little vague.

Also, if I 'skip' a level but still enter its checkpoint, is that allowed or not? Thanks

By "Clipping through the exit door" It means the final door to win the game after the boss fight. And skipping a level means not going through the checkpoint of the level.
