Yeah, I totally get what you're saying. That's one of the things we're releasing soon, the enemy scaling instead of just adding more enemies.
We still have to build a smoother learning curve, but yeah this game is supposed to get stressful and overwhelming at some point, because each run goes on indefinitely and it just gets harder. It's a fight to the death. Story-wise, the Countess was innocent and came back as a vengeful spirit to inflict on her executers everything she was accused of.
