Oooooh, thank you very much for your explanations! I played it again and it's really fun ! I've reached round 8.
I also went back on the tutorial and it's really strange, because the first time, the tutorial stopped after I through the dice. I never saw the part about money, bonus and defense, and I was really confused. I don't knowif I did something wrong but your tutorial is in end very clear.
Sorry about that !
