Detention review
The Good:
Deep, layered story; original setting with beautiful 2D graphics; simple, elegant controls; effective dream world puzzle implementation; masterful use of sound.
The Bad:
A save-anywhere feature would have been appreciated; finale stretches on slightly too long.
Our Verdict:
Detention is a marvel of sight, sound, gameplay and storytelling; a highly atmospheric horror adventure that manages to accomplish more in its short playtime than some games twice its length.
