Cloudi already said most of my thoughts…
I am much more experienced with console/mobile gaming than I am with PC gaming (the only non-jam game I’ve played a lot here is Mindustry and that’s a strategy game that encourages pausing), but I still went through and completed it because I like a challenge.
One note, the Ashen Queen or whatever her name is was an extremely fun fight until she followed up on the SLime or Fireball attacks with her Dash since the noise from those attacks makes it hard to notice the Dash telegraph.
Getting one-tapped by everything is very brutal but it forces me to properly learn every boss pattern.
