I tried to make a map that would be truly puzzling, even for people who have already played the actual Portal.
I've had many players test the map for me to help find exploits that I could fix, so you don't need to worry about a broken map.
Only rules are that you have to start with a new character and delete your pickaxe. The portal gun is supplied in the map.
ACTUALLY FEATURES WALLS YOU CAN'T PUT PORTALS ON!!!
