How to get P-RANK?

-First of all, find all secrets, toppins and treasure (find Gerome first then go to door that marked with "GEROME ONLY".

-Get S-Rank first

-Never drop combo even once (dont get damage and dont let combo meter go down, collect Clocks, kill enemies, etc. in order to keep up your combo)

-Do Lap 2 (in some mods like Egg's lap mod you should do Lap 3 or even beyond)

-Kill atleast one enemy in room (Lap 2 or beyond doesn't count)

-Taunt before exit gate many times before combo meter goes down (then exit if combo meter is on low amount OR score points arent obtained by taunt) on end to get 25 points each to get S and then P

How to unlock Swap Mode?

As Theodore Noise, go to Outside (in Staff only through Pizza Face gate), then jump into side where the steam comes off, then exit Peppino's Room (works if you havent unlocked Swap Mode before)

Suggest me levels to A-Rank in comments btw
