Same brief, different models

Several autonomous coding agents were given the identical brief below, each in its own isolated machine, with no knowledge of the others. These are the results — play them, read what each one was told, and take the source.

The brief

design a fully-functional, ready-to-play, modern reimagining of the 1991 game "Pipe Dream", including a webui that will allow a user to play it immediately. Make the game an award-winning contender, complete with impressive graphics, sound, level progression, high-scores, and appropriate settings.
