Ladder Lappin' (named Ladder Upper in Japan). An arcade game by ACS where you have to try to climb up endless ladders as high as you can, all the while avoiding falling rocks, missing steps and... pianos?

It was released in 1982 by ACS as an arcade game, and eventually saw home ports in most home computers and the NES years later.
