I played through most of your set and I thought I'd give you some feedback. You're free to take what you want to heart and discard what you feel isn't appropriate, these are my personal opinions and of course biased 
.
In general, I had a good time with the set. You have a talent for sokobans and cool puzzles, which naturally translates into fun experiences. Personally, I would have liked for a bit more attention being paid to the layout and concepts of the levels - I would have liked if your levels, instead of mostly being a collection of puzzles had more of a theme and that they then would not carry such generic titles. I feel you have created some great puzzles, I would like them to connect together to even greater levels than they are now. Not really a major issue though, cause I really liked the set and had a lot of fun playing it.
1 SO
Easy and short, but a good warm up.
2 SHIPS
I think the monster patterns was really cool, but I didn't think it was that fun to actually play. But I prefer puzzles to dodging monsters, so that's my bias
3 SO 2
Nice little sokoban.
04 SYMMETRY
This level felt like filler. I think you could do without it.
05 LINE
This one was great! Excellent use of the wiring system without it becoming hard to comprehend. One of the levels where the brevity really worked in favor for it. My favorite so far.
06 MAZE
I haven't actually gotten around to finishing this one.
07 TIME
Very tight time limit. Bomb-dodging areas and monster areas was a bit mean to have when it's a level you need to replay a lot of times to win. I liked the general idea but those two things made me not like the level itself.
08 SO 3
Great puzzles, great sokobans, a lot of areas I had fun with figuring out. One of the most fun levels in my opinion.
09 SQUARE
This level was ok. For me it was kinda hard to figure out all the wirings. So I mostly winged it, tried out some buttons and made it to the exit without having to think too much.
10 SO 4
I can't for the life of me solve that last sokoban. It must be possible, unless you and Joshua are in cahoots
. I like the layout of the level, even though it feels like those turtles around the island are mocking my sokoban-solving shortcomings 
.
11 SPEED
Short, pretty good level. I didn't really have a strategy, I just ran and lured some of them into bombs.
12 IT'S A TRAP
Wow, I really liked this level! All rooms had great puzzles that really required you to think in new ways to solve, the type of puzzles you feel really accomplished when you figure out. I was stuck on the second and the last room for some time each, which is a plus.
13 TANKS
Very cool, experimental level. Had a good difficulty level, it wasn't too hard and gave me a much needed breather
14 ONE DIRECTION
As a general principle, I try to stay away from Chip's Challenge levels named after boy-bands, but I made an exception in this case
. I have no idea how you made it so that you won there. Cool little puzzle level, even though levels like these always come across a little hodge-podge when you're not using all the elements on the map.
That's all the levels I got through, will get you more feedback when I complete the rest.
