 I suddenly realize I'm a cat and the other person an even smaller critter, I don't know what. It was obvious that the creature was just playing with us, watching our futile efforts to escape for its amusement.

+The other person tries to get the door to open again by messing with its circuitry, and I do my best to block the creature's view from what was going on without looking suspicious.
 
-After a while, I start exploring the room and notice that there's a hallway in front of it, also separated by a glass wall and a door. However, the wall is broken on one place and has a hole large enough for me to jump through. So that's what I do. I land in a bunch of glass disks lying on the floor, breaking them, but I'm unharmed.

-Now being a human again, I take a glass shard with me and run through a door which leads to a staircase. It's a large round room with stairs along the wall, so I can see all the floors coming before and after. It looks like there's an infinite number of floors.
+Now being a human again, I take a glass shard with me and run through a door which leads to a staircase. It is huge, having the shape of a pill with stairs going along the edge. The center is empty so I can see all the floors coming before and after. It looks like the number of floors is endless.
 I know the creature will come after me soon and so I run upwards as fast as I can.
 
 I made it about 5 floors when I hear a door burst open and I quickly enter the room next to me, hoping that the creature hasn't seen me.
