For a free, community-made, standalone mod, Portal Stories: Mel is an incredibly solid and polished experience. It plays like a full, Valve-quality Portal campaign clocking in at 7+ hours playing time.

The puzzles are mostly on par with the Portal 2 experience with a fair but challenging difficulty curve. A few of the more difficult sections require the player to find new ways to exploit game mechanics that they may have taken for granted in the original Portal games. Multiple times I found that thinking "How do I move that cube from Point A to Point B?" was asking the entirely wrong question.
