Fun and chaotic traffic manager! I like how the map animates in. Sometimes I was a bit confused as to what caused an accident, but the police officer mechanic is a nice touch and makes it quick and easy to get back on track. Such a good design decision to help players quickly get back into the action and not feel overwhelmed by cascading pile ups. This is a really promising prototype and ripe for future iteration. Nice work!
P.S. - Not sure if they weren't implemented or if it's a problem on my end but I didn't hear any sound at all while playing.
