Nice gameplay, I enjoyed the few rounds I played. It took me two rounds to figure out I could right click to mark people. It became slightly easier afterward...
My two cents : I think that the replay-ability of the game could be improved by adding some diversity in the building generation. All the buildings I got where 4 to 5 floors high and 4 to 6 rooms wide. Skyscrapers of 8 floors with 3 rooms each and/or more complex structures (a main building of 5 floors with 4 rooms each, with an annex of 2 floors with 2 rooms for example) would add some visual variety.
