I have to get used to the fact that if I don't have the cursor dead center of my screen, or holding Z down always, Samus spins slowly around. I mean even slightly off dead center and spinning starts, albeit very slowly. But still, I shouldn't start to spin unless I am closer to the left or right of the screen than closer to the center.
Also I don't really find a difference between the three sensitivity options, but I did have to turn the free aim off because it was really making the first group battle in the beginning of the game nearly impossible because my lock on weren't actually locking on. It pretended I was locking on, but my shots fired were going elsewhere. Once I turned free aim off, it was smooth sailing from there (sort of, still have to get used to dual control use)
Also, I miss the ability to lock on and attack enemies that I can see. I mean in the above battle where you have to kill the pirates to get back the power cell I can be on the ground floor and see a pirate up above in the open, but I can't lock on, or shot it even though it's right there. No wall seems to be between us. Oh well, I will get used to it, it just seems that for every so called addition, there is something that was taken out.
I died once so far, on the first boss, but that was because of not falling into it's pattern. Second go around and it all went okay. But I will say that targeting can sometimes be a little off. I wish they had made the lock on signal either brighter, or larger so that I can tell for sure that I am locked on to what I want to be locked on to.
Shooting in this game is better because of being able to shoot where I want by moving my hand, where as in the other two it was done with the control stick.
Also, my game is already set up to share my Metroid info. =D I just can't tell what names are black or grey. Nintendo and Retro sorta chose poor color coordinations in certain parts. Also, why isn't there any reference to this in the manual?
