I didn't think I would color this, or at least color much, but I will (a bit)

It's a 7d version of Portal....the 2nd one to be exact.

I've never played the 2nd one, and barely played the first one, but I sort of understand the game.

So, here it is

Dopey: Chell
Bashful: Wheatley (that round circle with the Bashful hat)
Doc: GlAdOs (that big thing)
