Pic related but the entire game (outside of matt's range) is echolocation.

something like this but a third person beat em up, like batman or sifu. the only time color shows up is when the dialogue or scenes are from a person's perspective who isnt matt, OR when a character is being introduced into the story who isnt matt. its 75% beat em up, 20% ace attorney and 5% visual novel.
