I've made a map that has a lot of well-thought out design, eg design that puts a lot of thought into the puzzles, instead of just trying to make it look pretty.
Basically, it uses techniques like misdirection to put you off, and I never repeat anything twice. Each room has it's individual puzzle.
PLEASE DO NOT TELL ME I AM UNFAIRLY KILLING THE PLAYER.
I'm unexpectedly killing the player. There is a huge difference. You just gotta observe how I kill you, and then avoid that happening again.

It autosaves, so don't quicksave or it might mess up some stuff.
Eg, if you quicksave after activating the trigger next to the box that opens the door to the headcrabs, then load your game the headcrabs will no longer instantly kill you if they bite ya. This is due to the fact console commands starting with sk_.. aren't saved when the game is saved. I guess you can do this if you're having trouble, coz the headcrabs battle often relies more on luck than skill. Or, you could just keep going without killing them, and they'll all just catch fire anyway.
Let's face it, very few of you will actually get both or even one of the solutions to this map, so here's the walkthrough, with both solutions:

I spent a LOT of time playtesting this map, so please don't just disregard it 
But rest assured, there will not be a volume two, unless people want me to, of course XD
