You are John, a rebellious teen who never learned anything in school. Now he has grown up, and one day when he wakes up he finds himself on an island. Knowing nothing about the world, he must find his way through the evolution in the hope of returning home.

Controls:
WASD - Move
P - Pickup message
E - Search for stuff around you
Q - Use a skill (Woodcutting or Fishing)
I - Inventory menu
Mouse Left - Fire the gun

My tips:
Look at the Inventory Menu frequently, it really helps solving the "puzzles".
Always read the message found on every map!
