This mod is okay. Some smart work was put into this, and the instructional videos are terrific. The rest of the art is a mixed bag, however, the theme of a next generation of Aperture Science is solid. The puzzles are meh, in my opinion, but they show off the new mechanics. The mechanics are not the most original idea (the time travel is just a clone that performs the actions you record), but the devs fit them nicely into Portal 2.
It's worth the hour or so it takes to finish.
Also, ball and box receptacles are "magnetic." Damn puzzle had me floating my clone in the air to hold the ball up.
