Surface Meltdown - Puzzle Edition

A playable version of "Surface Meltdown"! This fantastic map was originally made by Tewan & Mystical Ace for the 'Thinking with Portals' mapping competition "Picture Perfect". Here is a link to the original map : https://steamcommunity.com/sharedfiles/filedetails/?id=2193642857

This puzzle edition allows you to explore almost every area that was not accessible before. I also wanted to keep the design and atmosphere as close as possible to the original map. As a result, any difference or new setup is made for the purpose of the puzzles; and can be considered as a clue :) The puzzles are for experienced players, but no ninja moves, nor throwing of cube etc, are necessary!

The 3 things you should know before playing :

1. By exploring a little, you may find 2 secret passages, as well as 7 Crystals that can be collected. 2 of the Crystals are to be found in the first area (Indoor). When you leave that Indoor area you cannot come back later; so don't forget to search for those 2 Crystals before leaving to the Ravine area :)

2. The next area (Outdoor) is the Ravine area. The Bottom of the ravine is an additional area that you need to reach via an elevator (not by jumping or you'll die!)

3. If you wonder how to reach a high light bridge when you have nothing to climb on : jump & shoot will do.

If you're not sure what to do next, ask for a clue in the comments. Any feedback welcome :) Have fun!
