Tried sparring with rules setup as turnframes 1 and reactiontme 3.
It was suprisingly doable, with some practice I think I ttally could play this just like normal spar. As the replay goes on you can see me getting more used to the play style, though there's sill a lot room for improvement.
I didn't check te clock, but if I had to estimate I'd say it took us just bit over an hour.

EDIT: apparently the replay was too big to be uploaded to the forums so here's a cut version.
