The 30th game a day game is Elevator Action on the NES
You are Agent 17, codename: "Otto", a secret agent for an unspecified organization or government. Otto enters a 30-story building at roof level and must work his way down to the basement, collecting secret documents whose locations are marked by red doors. Along the way, he must use the building's elevator and escalator systems to move from floor to floor and avoid or kill the enemy agents trying to stop him. After picking up all the documents, Otto can escape to the basement and drive away in a waiting car to end the level.
