Elevator — free browser game

You're the elevator operator in a five-storey building; your goal is to take passengers from the floor where they start to the destination floor written on them. Click or tap whichever floor you want to go to; on the keyboard you can pick a floor directly with the 1-5 keys, or move one floor at a time with ↑/↓. Space or Enter starts the game, R restarts it. When the elevator reaches its destination the door opens: those waiting on that floor board in turn (cabin capacity is 3) and passengers whose destination is the current floor get off — each passenger who gets off brings +1 to your score. Above every passenger's head is a patience bar; the bar is green when full and turns yellow then red as it drains. Patience drains quickly while they're waiting and twice as slowly while they're in the cabin; if any passenger's bar runs out, the game ends. As your score rises, passengers arrive more often and their patience grows shorter. Tip: group nearby floors together to pick up several passengers in one trip, give priority to the passenger with the reddest patience bar, and keep driving the cabin in one consistent direction to avoid unnecessary turnarounds.
