With this one I was attempting to make a few 'open' spots to:
a) mislead the player,
b) allow for exploits which could give the player faster solving.
My one gripe with the original portal 2 levels is that they included far too many hint panels and were too restrictive. Admittedly, the final squad were a bit of a toy instead of an actual challenge.

Thanks for the feedback! I'll try to be more restrictive with the levels.

Good multipurpose use of an element, and the ending is an especially nice touch, but a couple of exploits hold it back:

• Player can jump/walk from white-surface to behind the squad without dying, breaking the more interesting puzzle elements;
• Vertical Light-Bridge origin location somewhat hasslesome to player; swapping ends would be more convenient;
• Some 'hint surfaces' do not hint;
