I like your theme, but in the room with Double Tap, I can't buy the sofa debris, so there's hardly anywhere I can go other than the tunnel which leads to Juggernog. There's not enough space to move in the first room, either.

You can open this door 

When you say maybe an easter egg  Please say that means yes.  I spent like a couple hours and didn't find anything, so if there is an easter egg can you give me a hint on where to go or if there isn't one please don't say maybe.
