All in all, the game is either so streamlined to the point where there is no challenge, or buried under it's own mechanics. Even then, the way gameplay and the story interact is... how to put this gently... somewhat stupid?
The biggest example is in the Pyrosphere, the obligatory lava/magma/volcano/fire world. Several times throughout the level, you take constant damage due to the extreme heat. After rushing through these dangerous areas and almost running out of energy several times, Adam authorizes the use of the Varia Suit when you are about to face the boss. This means that
you never had to take any of that damage in the first place. So, Samus needlessly risked her life
because Adam did not order her to use something she already had which he could do at any time!
