We played this at practice the other day when only 4 of us made it, most having gone home for easter. We thought it'd take ages, but in actual fact only took us 40 mins to get a full game in (starting at 501). Was great fun, and not really that hard at all, apart from finishing on the right double, now that was tricky...
I'm still in the process of getting used to my clicker, and found it a great intermediate step from blank boss to a target, as you can't aim TOO hard, because the black and white makes your eyes go swirly
