Yea, Level 3 will be more technical and include rocket jumps/ other types of jumps.
This works because when you go through a portal, you continue out, at the same speed you went into it.

Newbpal, Funny that you mentioned the "teleport from level to level" I`m not going to discuss it yet, but I`m actually working on something that goes along those lines. I`m not sure if you`ve seen it, but definitely search for Insidious` H1 Maptacular. Absolutely amazing, and is the main influence on this upcoming project. I just didn`t want you to think I was stealing your idea
