UPDATED: The cube funnel doesn't get jammed anymore. And even if it does, the jammed cube will disappear and the next cube will drop.
Extract 3 tricky boxes to escape.
Average completion time: 7min (once you've figured it all out)
There aren't any new devices, but it is full of puzzles that challenge you to use familiar items in new ways. This is not a reflex-twitch map. There are no double flings. This chamber is for those who like to solve puzzles. I'm making it because--let's face it--Portal is too short. So I hope that when this level is finished, it can satisfy you with more good ol' Portal fun.

This is NOT finished, so I'd appreciate your feedback!
Tell me if you find a ninja solution, etc...
I would especially like to see your first-runs and solutions posted on YouTube.
I still have to:
1) Add auto-saves, music, and metal boxes sticking out from the metal walls.
2) Find the right sound file for the pneumatic lift.
3) Make the moving platforms look more like the originals.
HOW TO INSTALL
1) Download from the link above
2) In Portal, choose "Bonus Maps"
3) Click "Import Bonus Maps..."
4) Navigate to wherever you saved "BoxyTrixyBeta.bmz", and open it.
How to uninstall:
1) Go to "C:\Program Files\Steam\steamapps\<your-account-name>\portal\portal\maps"
2) Erase the "BoxyTrixyBeta" folder


I was thinking about including an extra box dispenser in the main button room to take care of lost cubes, but I like the idea of putting a cube back in Room 2, like a penalty for being stupid enough to throw your hard-earned cube into a fizzler. I think I can distinguish Cubes 1&2 from Cube 3 by making that fizzler into 2 fizzlers (an outer fizzler that triggers Room 2 dispenser, and an inner fizzler that triggers Room 3 dispenser). But I would make it look like just 1 fizzler.
