Hi Luc! First of all let me say that I really appreciate your work and it's finally great to see someone who is willing to give back what he has learnt without expecting anything in return.

As you can see in the screenshot I have drawn two bases. The blue one is the first base and the green one is the second one. My question is if the first base never gets broken, can we jump and use the second base or should I wait for that first base to crack?
