I've been trying to score less than 180 seconds in the hard levels and less than 120 seconds in the easier levels. So in order to have tons of speed , use the Tanooki suit in order to complete levels faster. If you use Regular Mario/Luigi, Boomerang Mario/Luigi, or Fire Mario/Luigi, that's just gonna waste some time. Every time I streetpass other Super Mario 3D Land players in a Wi-Fi, they get jealous because of my scores. I scored 19 on 1-3, and the ghost house levels, I always score under 60. I also scored 115 on Bowser's castle in World 8. The lowest I scored was a 4 on 7-1. I give this a 10/10 because I'm a speed demon on this game.
