How easy/hard is Metroid Fusion?

[Metrium]

Personally, from someone who played all Metroid games except the first 2 (need to get on those one day), I'm currently playing it and I think it's pretty hard.

The game does a great job to always show you where to go next w/o holding your hand by showing you how to get there, so I think it's perfect for that aspect. I'd even say that Fusions' hidden passages are usualy a little easier to find than Super Metroid but they are extremely similar in that aspect so maybe it's just me being better than I was when I was playing Super Metroid lol.

But the tricky part is the battles. Maybe I just suck at it but in 2D Metroids, you are bound into taking dmg, that's a given. But enemies hit you so hard it's rediculous. A single hit from a random ennemy can take away nearly a entire tank (100hp). Meanwhile, to regain health, those health you get when you kill monsters usualy only give around 10hp, and these hp that you have to grab runs away from you and if you wait to long to grab it it will turn back into a monster (often right at the second where your about to grab it so you run into the monster taking dmg). So because of all this, it's really hard and at times frustrating to keep your health up.
