Detention is thought-provoking point-and-click adventure about a girl trapped in a creepy school building trying to escape. Set in 1960s Taiwan during a period of martial law and political repression. The game is very abstract and tells the story of the girl, her teachers, and her classmates, all of which is implied to have happend in the past, and we're exploring their story in a dream-like state.
It's very creepy and disturbing but very artistic and abstract. I'm glad I played it. The two endings complement each other very well, the Normal ending shows the girl's side of the story while the True ending shows the "reality" of what happened. I'm glad I got both endings!
