One of DigiPen’s most famous student creations, Narbacular Drop is a 3D puzzler starring Princess “No-Knees.” Using two interconnected portals she can place on walls, ceilings and the floor, she must navigate her way through a sentient dungeon named Wally.
Very careful attention to detail and an enjoyable puzzle make this map stand out from the crowd.
This map is very confusing and takes advantage of a very obscure mechanic that most players might not be aware of. According to KDAPro on Nuclear Monkey's forum:

"Yeah, basically using the ceiling your meant to use Portal through portal to reach the box then escape.
I havent a clue how to counter using the camera to 'cheat'"
"*spoiler*You need to get the portal above the box, then place the portal you're portalling through through the barrier, and portal the crate from there*end spoiler*"
An interesting solution !
Cheers.
