The City has some great descriptive writing, but suffers from a few problems.
You wake up with amnesia in a mostly empty area and follow a surreal plot with a What Happened? ending. This has been done in shows like The Island, in short stories, and many times in interactive fiction (although this is an early example). The City doesn't bring much new to the table plot wise.
The game is short enough that the author felt justified in disabling save, restart, undo. This had an interesting effect on the atmosphere.
The puzzles were highly unclued with some guess the verb problems.
This may sound like a negative review, but the descriptive writing was a joy.
