Beautiful game! I was a bit of a dum-dum not understanding how to block the doors. I initially though that they had the same mechanic as the windows, and all that I had to do was put a can next to it. I tried pushing furniture up against them, but I was expecting a progress bar so I didn't realize I was doing it right until I noticed the score =P
I did eventually figure it out though, in spite of my ineptitude. Truly visually stunning and neatly made. Well done!
