JUICE: I like how the mud (?) deforms as you look at it. The victory cinematic was also very satisfying.
Gameplay: It's barebones, but I saw you said you lost time to something else. I think prioritising visuals and feel was probably the right decision.
Graphics: Really pretty! It's nicely immersive as well. You could have done this same gameplay in 2D, but it feels much more interesting to be in the level.
Sound Design: I liked the watery sounds, and chime as you pick up a crystal is nice.
Respect of the Themes: Not really sure how this related to either theme. I guess it's limited, in that there's just the one level, but that didn't seem deliberate.
Overall, an intriguing experience. Hope you find time to expand it into whatever your original plan was.
