For the Portal lovers out there wanting more difficult puzzles, I believe Portal Reloaded will scratch that itch for you. The extra layer of complexity added by the third portal really makes for some brain-melting puzzles when you're first introduced to the mechanic. That doesn't lessen the fact that the later puzzles are still very difficult; I would say even more difficult than any puzzle in the base game (Portal 2).

One thing that the game can improve upon is the explanation of the different colored energy fields that you can walk through. You know, like the blue energy barriers that blocks portals but not the player? I remember seeing an orange and green one too and I don't think it was ever explained on what they do. That left me stuck on a puzzle until I figured it out by accident.

Note: There is a bug that I came across in the first puzzle using the light bridge. The future cube did not spawn and I could bring the present cube into the future. What fixed this bug for me was to go back to the main menu and select the appropriate chapter (I think it's called "Light Bridges") to start over.
