Zombra
An iron rock in the river of blood and evil
Yeah. Sadly this is like one of those games where they let you turn off quest markers, but the game is basically impossible to play without them because there's no other navigation system in place. I'm constantly tapping the button to turn that back on temporarily, and also my health bar since there's zero feedback between 100% hit points and dead. Plenty of diegetic ways they could have communicated this information. Hell, diegetic health info goes back at least as far as 1996 and Resident Evil. Maybe next time.
