Thanks for the comments! I'll take those on board and make a few tweaks.
You need to find something outside the stadium to make the bouncier shoes.
If you're talking about the springs, I found them but I don't know how to use them... (English is not my language, and I can block stupidly on the use of a verb or simple way of doing things).
Try 'attach'.
Thank you. I tried: wear, insert, tie, fix, place but not attach!
Book issue solved, version 0.1.1 now up. Thanks again!
