26: There are some really fun tank puzzles here. The starting sokoban, and the final room, are my favourites.
28: It's a decent level; I especially like the tank room.
29: A clever puzzle, surprisingly hard.
36: It took me a while to figure out that I didn't need to hold down the trap buttons It's a fun sokoban.
37: This level was surprisingly hard, but it was fun; I especially like the tank room.
39: Decent blue wall maze.
40: There are some clever puzzles here. It's a decent itemswapper.
41: I love the blobs on fire and the recessed walls. Really nice level.
42: This was a decent maze, and quite hard I think.
43: The blank hint tiles slightly annoys me. However, I really liked this level, and I agree with Miika that it is your best Walls of CCLP4 contest entry.
45: Really fun key level
46: Really good-looking maze concept; surprisingly hard.
47: My favourite rooms are the toggle/block room (nice use of ice under a block) and the pink ball room.
48: There are some really fun puzzles here.
49: This is an awesome compressed level, and I like the pointless chips and socket, as well as those sevens only visible in the editor and the 77 time limit.
50: I have already seen several levels using this concept, but this is one of my favourites.
51: Yeah...the title IS disturbing...it's a fun ice maze though.
52: Really fun puzzles. This is the type of level, however, that would work better in CC2 with bonus flags.
53: At first I misread the title as "Paranoia Ranch". I'll probably use that title. Anyway, this was a fun level, and it had some nice puzzles. However, it is not necessary to press the tank button; is this a bust?
54: Nice level with a strict time limit; I especially like the teeth, walker and partial post sections.
55: A really fun level.
56: One of my favourite levels so far in the set. Very creative use of teeths.
57: Better than Unmitigated Hint Factory Disaster.
59: There are some fun puzzles here, but I'm not a fan of the glider/fireball room at the end, it's easy to cook and at the very end.
60: A really creative puzzle. One of the best levels in the set. However, I managed to solve the level without using the recessed wall at (14,28).
62: This was a nice twist on the original concept, and I like how some blocks need to be pushed into water.
64: Decent pink ball level. I'm not really a fan of the skate trick at the end though.
65: Really clever awesome trick to solve.
67: A really amazing level, the title is very appropriate, and the ending block puzzles are very clever.
I haven't solved the other levels yet, but I will leave feedback on them once I have
