Unless I'm missing something, Acedior is the shortest demo I've ever, ever played. The demo allows you to look at two rooms, talk to two characters (one off screen) and then boots you to a 'thanks for playing!' screen.
It literally took twice as long for the program to install to my handheld than it did for me to 'play' the demo.
Perhaps they found an even more obtuse adventure gameplay mechanic than I'm overlooking, but for $25 I'm hoping for a demo that shows me a bit more than three minutes of game. Maybe I should finally boot up that Bone demo.
