I get a Metroid Prime vibe. It's pretty chill and I can really see this as like an underwater area in Metroid. I really like the snare you have. It's pretty sweet for the theme you're bringing across.
Two things I hear with this that I would change. The synths you have are good, but they're not solid. I'm specifically talking about the lead synth and the little whistle at 00:54. All of the synths do their job well (especially the bells. Those are perfect). The lead synth is really cool when it's quiet and chill, but it doesn't feel right when it gets closer to full volume. The whistle, like I've said is played correctly, but it just doesn't feel right like it needs reverb or depth. The second thing I'll point out. 01:38-end just feels awkward. It's not bad but just ending with that doesn't feel like it works.
Anyway, those were my two-cents. Bottom line is it creates a sweet feel, actually does inspire some imagery. It could be a little simple, but still could use a little work either way.
