Nice, I played this game on PSN a few months ago for the first time and of all the things the game does well is the amazing soundtrack, I couldn't believe how well they could create the atmosphere for their respective areas. The graphics looked surprisingly good since I really liked the art style and the various special effects some of the weapons/shields had.
Sure the voice acting was bad, but you could just laugh at it and/or ignore it, not like it had any in-depth story anyway. Probably what bothered me the most was the serious imbalance in difficulty, at the beginning some bosses could be hard but after getting to the inverted castle there's pretty much nothing that could present a challenge for you anymore, especially if you got the Crissaegrim. It just goes to show what I think; a metroid style game is at its best when it's really close to actually being metroid, like Cave Story or Arkham Asylum, RPG elements have no place in it.
