No stage select routing (on normal) for a Baron-less run from Level 1 thru B2, then Happy Ending (i.e. two-players on screen). If you're unsure about a level, just game over and try again. (I did not do this but) If you're really in doubt, use stage select when you game over to revisit certain levels to farm for special items; then, game over and go back to the problematic level you'd like to quick-clear using said items. (Umbrella: 15-20 water bubbles; Bomb/Book: 15-20 fire bubbles; Tiara: 15-20 electricity bubbles)

Levels to try to PRACTICE or SKIP: 43, 57!, 68!, 71, 81, 83, 87, 96, 97, 99, A0, A6 and B0. 
Best levels for umbrella warps: 5, 20, 49 and 64. 
Best levels for fire/electricity bubbles: 53 and 80.
