Hurry up repentance+ on switch 2
I played as Samson, hard mode, got to sheol and defeated Satan. Was shocked that I even made it that far in one run.
I think I made some progression and got a bit better.
I also managed to finish a run as Blue Baby only to realize you need 11 kills and then play as Blue Baby to get D6 
It's been brutal but I think I will do it before the weekend ends.
As you said, I'm having so much more fun now that I unlocked a bunch of better items.
