Ontological Mystery; or, lack thereof

Ontological Mystery; or, lack thereof is a slick point-n-click mystery piece made in Decker, where you find yourself locked in a room with a dead almost-carbon-copy of yourself and a blade in your hand. What will you do next?

You can explore the locked room for a while, your own self and the body lying on the floor, before a timer finally opens the door and you are left with a final choice, each revealing a little piece of the mystery. Because of the timer, you need a few replays to see all there is in the game and to piece out all there is (though much is still left unresolved). And the illustrations were neat, being all black-and-white-except-for-that-little-detail. A really cool piece.
