Quite an original idea that was well executed. Fits to the Game Jam theme.
Choice of Ambient music and SFX really add to the atmosphere and build tension. Art style is minimilistic but effective; the flashing effects for the emergency vehicles is really on point. Colour palette is good too, colours mesh well together and the emergency call icons stand out.
For improvements, I think adding some more icons to the report popups would be benefitial. Namely, how much the disorder/tension bar is affected and icons for what emergency vehicles had what effect. Just makes it a bit clearer to see what's going on at a glance.
Nevertheless, a very strong submission that I enjoyed playing to the end. Excellent job!
