Commentary

A classic. I like how it manages to unify, to an extent, using the "construction set" to build your own levels, and playing the level (since playing a level essentially means to complete its construction satisfactorily.) I also like how it naturally accomodates multiple solutions.

People sometimes tell me how RUBE reminds them of this game.

Every so often, in a television commercial or similar, I hear the exact same squeaking sound that the trapdoor made in this game, and I have a flashback to it. (That sound sample must be in the public domain or something.)
