The Aperture Science Symbiotic Ascension Course

My entry for the mapping competition. Now, this is my first co-op map, and I found out about the competition much later than I would have liked. So there's a few buggy things a would have fixed, but didn't have the time if I wanted to enter. So don't throw any combustible lemons at me if you discover problems with it, chance are I already knew and didn't have the time.

This is really a simple puzzle. It loops in on itself with obstacles; unless you and your partner can work together, you're both going to be doing alot of exactly what the title says.

This is my first co-op map that I created. In this map you must find the way to open the exit. Should not die or do the first test(in 1st) again. You have to manage gel to do what you want.
