Here's my skill 2 demos.
Breezeep: Very cool little map, reminded me of the very first retro jams with the small squarish layout and classic id textures.
Dumptruck: Clever map with nice watery bits. The puzzle was a bit too "you need perfect timing" for my old bones though.
Ing: Sorry, the difficulty was a bit over the top for me so I didn't finish (despite several attempts), though I liked the unapologetic design of it.
Ionous: I guess true love never dies. Good vibes with the colors until I looked up. Would have been just the perfect length for youknowwhat ;-)
Jazz: Surprising amounts of detail considering the size. Got flummoxed and died to a Fiend early. Good overall, nice work on the textures too.
JCR: Splendid use of gravity triggers, combined with the layout and the unusual texture use it reminded me of hipnotic a fair bit.
Nostalgick: Welcome to Quake. This map has all the markings of the author learning mapping on the go (in a good way). Decent overall.
Yoder: Sorry didn't finish either, didn't figure out the puzzle, especially since I couldn't resist that one secret. Good lost temple vibes. More!
