Replayed it, definetely was more interesting expirience with 4 rules (dunno how i managed to stay with two rules in my first play..) But i think speed doesn't help player analysis, if it's where you going. Personally feel, like it doesn't add complexity. I would decide what game focus i want: fast reaction decisions or slower analysis (ofc its only personal opinion. I think there are players who likes all at once challenge)
Overall - great game!
