Yeah, the title pretty much says it all. Portal 2 finally got a level editor, I got interested, tried that out, and made my own level. Medium difficulty, almost entirely death-safe design, and a "that thing
must be there for a reason" kind of puzzles.
The whole creation process consisted of:

One day of building, and about four days of fixing and updating it all the time, because of unintended solutions, traps and accidental deaths;

Having to wait about 10 minutes to let the level re-render itself each time I wanted to test the changes I made, even if it was just adding an additional second to a timed button (yeah, because it was impossible for Valve to make a system that only updates already existing render, instead of recreating it from scratch EVERY SINGLE FREAKIN' TIME);

Managing to go from being halfway into "Harry Potter and the Prisoner of Azkaban" to finishing it and starting the "Goblet of Fire", just by reading it every time I had to wait for the map to re-render;

Realizing how weak my PC is, if the process of rendering makes it choke up so badly that EVEN MOVING THE CURSOR BECOMES A SLIDESHOW;

Bothering my friends through the chat, because nobody seemed interested in trying out the level;

Going from "don't go in there, or you will die" to "the player must not be able to kill himself" design over the course of countless updates;

Learning that laser fields are pretty much useless, and Valve has to make a barrier that stops player without killing him, and only lets objects pass through it;

And probably some other minor and possibly annoying/stupid/informative/funny/whatever stuff that I could point out but don't remember it right now.
So, uh. Anybody willing to try out my level and leave some feedback? Please? It would be very greatly appreciated. Especially if you were to actually write a constructive critique, that's always great!
