Thanks for playing and the feedback!
Regarding the intercept, I will try and clarify it further in future releases.
But if you wanted to know more, basically, each unit has its own intercept cells , and kicking through them will trigger a dice roll, and if the roll is higher than the number above it will steal the ball and get a free turn. Stats, items, and abilities can influence the intercepts. There are also some units that have move intercepts, which, if you walk through, is the same idea; they will push you and take a free turn if they roll high enough. (blood bowl-like).
