@The:
What ended up being your death count and total play time in the end? After attempting Hilda Berg and getting no where after an hour, it was definitely not a challenge I was up for, so massive props for completing such a game.
Well, technically the death count for the S-rank run is pretty low, maybe a dozen at most… but that's because the way S-rank works, the run is dead the second you get hit, which is where you just restart. Therefore, what that fountain tells me in regards of deaths fails to really convey how much trouble each boss gave me. The number the fountain gives me would me 95% deaths from my co-op run with foo in regular.
In terms of time, steam tells me I'm at 64 hours with the game. Notably tough bosses were Hilda Berg and Wally Warbles, each taking two hours each; Dr. Kahl's robot taking a stupid 6-7 hours, until I slept it off, then came back the next day and got him with cheese strats pretty quickly; King Dice taking two hours, but then part of what takes long in that is having to redo the mini-bosses; and then the Devil, who took about 4 hours and thirty minutes, after not one but TWO TIMES of getting hit at the same exact frame in which I killed him, which is one of the most gigantic slaps in the face this game can give.
Outside of those bosses everything else felt manageable, though a couple (Cala Maria, Cpt. Brineybeard, Phantom Express, Rumour Honeybottoms) I would not want to have to do again given just how much reliance on RNG they involve. And then there's Werner Werman, who I killed without damage the first time and had to retry for like five to ten more minutes just to get a good roll on the cycles in order to get 3 parries in the beginning.
