It's an original and very enjoyable game.
I got six out of ten medals, but now I'm stuck because I don't know how to make or get the bouncier shoes (the game is quite simple though).
Some remarks :
When you talk to the coach, the first menu "Want advice? Yes/No" may be too much.
I always get the same message "... now!" when I read the book.
When I try to climb the apple tree, I get the message "not understood."
