Dear FlyorDie!

In the recent years curling has improved with some new rules (in real life), so it would be good if you implemented these rules (especially the rouls that limiting the number of tics up to the first five stone throws on the center line (cannot be hit off the center line) and in the house).

*And PLEASE introduce only-one-side sweeping function! (to get the stone curl more)  :))

(Sorry for my english if i have made any mistakes)
