This game is absolute trash even for its measly 3 hours playtime

First off metal plus rhythm game is inherently such an awful match since the genre itself is extremely syncopated in nature which leads to the actual rhythm getting muddied by the loud instruments. Even though the game did try to rectify the issue by throwing in a crap ton of visual cues but it only adds to unnecessary visual clutter and in turn making the gameplay far less intuitive. But that's not the only issue the game has it also suffers from contradictory mechanics, cheap vfx and the environment/enemies around you barely reacting to the overall rhythm and yes that includes the bosses as well

Ultimately if you strip down the rhythmic nature (which it barely capitalizes on) of the game it just feels like a clunky clone of Doom Eternal
