I’m not. Well, probably not. If you own Portal 2, a Mac, or a PC, I’ve got some exciting news. Valve has announced the Portal 2 Perpetual Testing Initiative. Basically it’s a super streamlined level/puzzle builder for Portal 2. People have already created tons of them, but the process of sharing isn’t that easy. This will make it very easy to create and share with anyone and everyone. Just hop on to the puzzle maker, create your masterpiece and publish it to the workshop for your friends to play and be stumped.
