Great game!
So far only noticed one small bug (not mentioning strangely working default controls): some of the "Number of mines in the 8 surrounding tiles" with number 1 on them don't get grayed when they should (after all tiles around them are solved).
Can this be that the terrorists are said to wait for reinforcements in some area, but there is no virus in that entire area? I double checked every room and every body, but still there is no virus or further clues :(
