This map has every level design problem in the book when it comes to Portal 2. This map includes:

-Trapping possibilities with angled panels, unrespawnable cubes, and unable to portal out of ditches.
-Exploits by carrying cubes through doors and skipping intended ways to handle problems.
-Unused test elements like the aerial faith plates pictured, blue gel by using the cube as a turret shield, and cubes by using the said exploit methods
-Annoyingly placed turrets.
-Hiding antlines thinking that will increase difficulty when really it increases tediousness and trial-and-error guesswork.
