Made it over the course of a week in the style of Super Metroid.
For whatever reason, people tell me the styles don't match.
Whatever.
It looks fantastic, I think the style issue I that look at Samus, she has a dark-ish outline which I think follows suit to the rest of the game
I think the palette could be a bit more expansive for some eye-popping goodness. Blues and purples. Take a look at Sonic 3's ice cap zone.
