Sega, you don't improve ANYTHING. You don't care any of your player's review. The original Metal prototype hitbox is legs and torsos, But you make it harder, as I tell, spines are on his head, you need to be lucky enough to hit him without touching the spines. 2 Bosses with NO Star checkpiont, No rings to collect, AND Too hard. DED Egg robot's hitbox is too high for sometimes. At least 3 rings will be fine.
