Didn't think it was funny and tried too hard to be. Puzzles are a mixed bag, difficulty very inconsistent, no real curve but rather a zig zag. Way too much filler content where you're just walking around and looking for the next "portalable" wall.

Considering it's a free mod it's got very good production value and some of the puzzles were indeed excellent. Were it a standalone, regular priced game I would not necessarily recommend it, but it was decent overall.
