It's confusing in the apartment scene how you always exit to the same place when leaving a room, instead of being in front of each room's door. I also was hoping for something there rather than a bunch of identical neighbors.

It'd also be good if the key pickup was visible on screen or audible with a sound effect! (unless I missed it?)

Nice little game, but there some bugs that makes it a bit weird. But other than that great job! :D
