Portal 2Community Maps
As Portal 2 is one of my favourite games and it also offers a level editor, it was a perfect fit when I wanted to try out level design in 3D. Apart from trying to create an interesting puzzle I also focused on things like a good visibility of all the required elements, making the puzzle easy to solve once you know the right solution and preventing the player from "breaking" it with unintended solutions.
These are screenshots of my second chamber Think Twice which got very positive reviews. After a few playtests with friends I was also lucky to get lots of feedback from the online community so I could fix some issues that I had overlooked before.
