I was blown away when I realized that the building was 3D. I find the game concept quite interesting.
Sadly, however, the controls often did not seem to work well - I would click to move, and the game would just not register the click - which was frustrating.
EDIT: Ok, it's actually just one particular part where the controls are being weird, they seem to work fine elsewhere. I cleared the game.
I find it cute how the background is just a giant cat face.
