Needs work.
I mean no offence to the author of this short, but this piece needs some work.
Some of the sprite animations and positioning of the sprites in certain parts don't really make sense. For example, in the scene where Samus is running to her ship after getting the gravity suit, the placement of the sprite makes it look like she is running with her legs underground. Also, the scene where Samus' ship crashes into the mountain, the animation gets really big, then shrinks back to normal size, in a sense, crashing into, going past, then going back to the mountain and blowing up.
Also, the first missile explosion seemed really loud on my system, but that might just be me.
