I made this map when I was on my glitch spree. I was trying to really push the limit of what I could do in a level. I went and submitted it under the retired uncategorived category as well as an added bonus (thanks to templex). The level in my opinion is more of a great glitch level and not as amzing gameplay wise.
Fracture - http://numa.notdot.net/map/28613
This level was my first ever level where I put a constriction on what the player could do. The level is 1. difficult to complete and 2. has no exit. Still I think it is quite inovate and pretty fun.
4-1: Challenger Deep - http://numa.notdot.net/map/48469
From my attempts at episodes I think that this is one of my better levels. It was a pretty cool concept that I was playing around with and the result was pretty fun.

A cool swist on the whole "long passage run around and jump over things" type levels. I love the timeing that worked out and also the lower tiles that add some sparkle to the level.
Chill - http://numa.notdot.net/map/55832
Chill is one of my favorite levels. It is fun to play, short and sweet. I always like the style of the diagonal reflection and so when it works out so well it makes me very happy ^_^

I love the tiles that I did for this one as well as the gameplay.
Bread Crumb Trail: All you can Eat - http://numa.notdot.net/map/86566
This level was completly and accident. usualy when I make a puzzle map I have a planed ideas and have a pretty good idea of what I am going to do. When making this I made the traps and then added the gold to make it so the player could get through it. At that point it was incredibly easy. I was planning on just making a path to the exit but when I played the level I realized that If I made the player go back through the same maze they had just come from it would create much more a challenge as well as creat something new and inovative. I was really suprised and quite pleased with the outcome.

I overuse chainguns alot in my older levels. I have many that are ridiculously hard. But this one is much easier as well as more predictable and still posing a challenge.

I usualy stick to linear, closed levels. These, while sometimes being quite enjoyable in some cases, can be very boring. Even currently I strugle with making levels that let the player decide what to do and not driving a path from them to take that I have planned down to the last jump. This level I love becuase I can find a new way to play it every time and in many of my newer levels I strive to create a similar effect.
If You Don't Like Skydiving Settle Down and Build a House - http://numa.notdot.net/map/94957
My most recent map that I am including here. I started by making it a level that you would be live skydivng (like the falling part at teh begining). It kinda sucked so I built a house. Out of traps. And it got pretty big. Then I added alot more gold and mines and practicaly remade the level.
