This is primarily a reskinned of Super Metroid. The enemies & bosses are resprite. But the levels & art are new. Where it shines is the creepy atmosphere later on at certain levels and music. Though I was a bit bored by it's tame nature at the start & at varies time. This game reminds me of Yume Nikki. Wall jump is required. Early water levels suck. Don't like the blue light sfx. There are some minor changes to abilities. Story is told through by intro opening and 3 panel art... so non-existent.
