The Devil S Rank without jumping
Idea from @JimmyGamesFL
This was actually very easy for me to do, the only hard attack was the goat, mainly because you need to time your dashes if you only have enough cards for 1 crackshot EX, other than the first phase... not really much else I could say other than using the EX again to move from platforms in Phases 2 and 3... this took less than 30 minutes mainly because of bad RNG of getting the goat attack at the beginning and other areas where I made stupid mistakes, I would be lying if I said I wasn't restarting just to try for hitless... but overall a very easy S Rank to get even if you ban jumping. Are other bosses possible? Absolutely! Goopy is definitely doable and maybe more, but a boss like Rumor Honeybottoms is impossible unfortunately.
I could vent all day about this boss on Souped Up... aswell as the others...
