I hated journey to perfect until yesterday night, when I finally remembered my bat scrolls. Oh, they shoot missiles at me, but my +75% power legs let me escape them all. Bats don't even have legs, so this is kinda weird, but it's so much fun! The outdoor ones are too easy, you can storm dash across the entire top of the mission. Buildings are hilarious, because you'll have a constant barrage of missiles exploding on every surface for no reason, and it will lag horrendously. Cave missions are pretty similar, except you just have to dodge a few bats or similar.
So easy, so much fun, and hilarity ensues when you hit the switch at the end and have 100 missiles impact you while you're invulnerable from mission victory.
