Beneath the Surface (Baba Is You Levelpack)

Suddenly had a cool idea for a mechanic so here it is! A levelpack (made in a surprisingly short amount of time) about diving beneath the surface™.

This might be the first time making something relatively simple, as unlike other packs I've made, this one does not involve rewriting the entire parsing-time continuum...

Anyways go ahead, get ready, take a deep breath, and dive into the pack! 100% completion is 13/0/0.
