Another platform style game made by Electronic Arts for a variety of platforms in 1983. It was packaged in the flatbox style (a 9" box that folded out, about the thickness of a record). The authors were Michael Abbort and Matthew Alexander.
In that wonderful style of '80s game, the "plot" of the game was rather silly. You were a construction worker, and you needed to finish the unfinished building (really just girders). So, you grabbed sections of platform to pop into the unfinished holes. Stray rivets, OSHA workers, and other odd things chased you about, while you climbed up chains or used an elevator.
I was one of the people stuck playing on an old IBM PC back during the '80s, so this had some of the best gameplay that you could find for that platform, despite all its limitations.
