WHAT
WHAT is a 2.1 unrated solo level created by Spu7nix and verified by AeonAir. The level is a spiritual sequel/successor to HOW, being that most of the gameplay is in 3D sections. Unfortunately, you have to download a patch for the game that lets it store 4 gigabytes in memory instead of one. This is commonly referred to as the "4 GB Patch". The Low-Detail mode for this level stylizes it after 1.6-1.7 levels.
Gameplay
The level starts with a simple 3D cube part wth blocks being the only obstacles.
The wave part starts with a sequenced animation of the cube transforming into a Pyramid without any gamemode portals. The wave gameplay is nothing special, though the main difficulty of it comes from the isometric view of the camera.
A ship part follows a decent bit after, with gravity being stronger than the regular ship. This part, like the other 2, is still 3D, but focuses more on a vector-style aesthetic similar to retro games like Asteroids. (i can't write anymore, someone pls finish this page!!!!)
