The Variable Room

Is there no way to invert camera controls?

I found 3/4 solutions for the smart door, leaving me w/ only 4 possible solutions. I was stuck for 30 min and even started over thinking i did it wrong or the game glitched. I eventually found the 4th one and it opened with a solution i had already input.

Couple of typos:
Data Pad in Room 2 says "signs alien of life" instead of "signs of alien life".
Multiple instances of "draw" instead of "drawer" .
(Just realised that Blu-E gives you a random drawer number each time! Nice!)

I clipped through the floor in room 3 on a path that lead to a dead end with nothing else in it.
