Quick and easy This map is just about visuals so the puzzles are not very challenging.

Contest0108_Nameless_SimpleChamber
Short chamber, quality over quantity! This map is very short, I hope its length doesn.t cause any conflict with the contest. Its my first completed map in hammer and my 4th attempted map. I tried to make it as detailed as I could but I began near the end of January and I'm still learning a lot, so I hope you like it and any constructive criticism will be appreciated!

How I Learned to Stop Worrying and Love GLaDOS LoveGLaDOS follows the Portal campaign levels' visual style and gameplay relatively closely. It is about as difficult as the game's Advanced Maps.
