I will concede that the aiming specifically isn't S-tier, but then again this is an "action-adventure" game, not a shooter, and everything else in the combat system more than makes up for that one less-than-perfect feature. Not to mention the fact that the game is much more than just the combat system. "Action" was just one of the characteristics I listed. The aesthetics and paranormal lore are reason enough to play it regardless of any combat.
It's incredibly satisfying to destroy the environment, throw objects and enemies around, levitate, dash in mid air... just thinking about it has me wanting to replay the whole thing even if I already know the mystery.
