Mindshadow

You find yourself - all alone - on a mysterious tropical island. You have no idea how you got there or where you came from. You don't even know who you are! And now, armed only with your reasoning power and imagination, you must escape from this place and get to the root of this puzzle.

You awake in a hut on a deserted island, with a headache and no memory.
