Rightclick on the bottom right of the screen... You're invisible until the snake comes, so go to the left of the screen and dodge it by going in circles. Once it's gone, rightclick on the bottom right again, before the wall clappers come back. Helps with the impossible badge so much! (NOTE: Don't mouse over the screen while you're invisible, you'll re-appear)
As I realised what was happening to the boy, I actually felt like I was losing something. The beautiful, yet simple piano score added a lot to this game, while the symbolism behind the game was touching. My favourite game on Kongregate.
