ok so, i've come up with a few solutions.
One, i could reset the game back to square one, with new systems in mind and some last-minute changes to make the game better, though this would return the boss counter back to #1.
Two, i could skip this boss fight and move to the next one as if it never happened. (move to #22 boss)
Three, I could restart the current boss fight, with me at the wheel. (Restarts Battle against the Man of hands)
I'll do a poll for this, so you guys can decide on what i do.
