This game is good.

I heard this was one of the hardest games of all time. I played it for the first time and got to the final boss within only a couple hours of playing. Game overed on the boss, was sent to the very beginning of the last level, then proceeded to shut off the game. Not even Castlevania pulled that kind of thing, at least they recognized when enough was enough.

This game amazed me with its terribleness. Secrets that are hidden in manners you would find more fitting for Metroidvanias, one of the weakest weapon sets in the series, and severely lacking in the music department.
