Unbelievable amount of artwork! I liked that each floor was unique, and the characters were fun.
I think because of the artwork is so good, things like black backgrounds and the jittery animation stood out a little more than usual.
The game have lots of potential for the gameplay loop I think - at first I brought the laser to the cat lady, because I didn't pay attention to her poor eye sight - it was fun details. The other puzzles were a little too simple, and I would appriciate more. Great work!
