Sounds good to me! Or terribly confusing, or something along those lines anyway.
I am not exactly known as a NAP-lawyer-type-guy, and most^H^H^H^Hall games I run have a "NAPs don't really count" rule.
Anyway I expect the defenses of Jomon, and offenses, to be all-the-more spectacular, considering the extra turn you've had to prepare, then. Oh hold on, I suppose I had an extra turn too. Hope you won't be disappointed!
