HIGHLIGHT ENEMIES

The highlight option would be great to have on enemies so its visually accessible. Maybe its me, but I like the games dark aesthetic when I keep the brightness as default as possible, but enemies are quite difficult to see. Rather than a health bar over enemies' heads (which only pops up when they're damaged) why not give us the option to highlight enemies always.

Seconded. There's nothing more frustrating than dying to a mob because you glossed over it, thinking it was a normal enemy. To take it a step further, a clear distinction between player vfx and enemy vfx would be nice too. Sometimes its impossible to tell which things on the screen will kill you and which ones will.

Blasphemy + Curse (+curse radius).
Nearby enemies will gey a curse-icon over their head.
