Yet Another Portal Pack (YAPP) + Puzzel

This modpack does multiple things. With Immersive Portals, it allows you to go between areas seamlessly. With GravityAPI, it messes with your perception by allowing the alteration of gravity! With "another mod", it can change your size!

In this puzzle, you must use these portals to manipulate your size and orientation, to try to get to the end! Be warned though, sometimes things are not what they seem, and others can be quite hidden...
