being a fan a metroid I just had to review this
I like the fact that you used a enemy from metroid prime 2 (Dark Metroid).
But the metroids don't actually do damage, also I find its incredibly hard to actually hit them. by the way it doesn't seem like your properly beta tested this because I see no way to get out of the area with the morph ball bomb upgrade. it looks their is suppose to be a way out but it doesn't work - fix that
