JUICE: Sound and particles were good, but it would have been nice if impacts had been juicier, since that's the main thing you do. Some squash and stretch on the character maybe?
Gameplay: It's a nice one-button game, and collecting juice is a good bonus objective. I found it hard, but I'm not very good at these sorts of games. Overall, solid gameplay, and easy to grok.
Graphics: Simple, but decent. I liked the pipes. Very Mario-esque.
Sound Design: Good, but the music seemed to get gradually louder as I played. A bug, maybe?
Respect of the Themes: I hadn't considered mirroring gravity, but it's a good interpretation.
