Traffic

You run the lights at one crossing. One button flips which road gets the green, with a short amber and an all-red gap in between — so switching is never free.

Every car that clears the junction pays a point, multiplied by your streak. Cars waiting at a red lose patience, shown as the bar shrinking under them. When a driver runs out they turn around and leave, costing you one of three lives. Ambulances lose patience three times as fast and pay ten times as much.

Clear cars without anyone turning red-hot and the multiplier climbs. Traffic keeps getting heavier, so the run ends when the third driver gives up on you.
