Excellent, simple game with tons of polish and nice touches. The sound FX are subtle but present for everything. The music is chill, and the background wave swoosh is nice. I also loved the art -- a beautiful beach volleyball court in a summery, partly cloudy sky! Great squish animations and small but noticeable shrink on the ball. Excellent choice of water shader. Gameplay is simple, but compelling. I just wish it was networked multiplayer so we could all see who's best! My only feedback is to consider changing out the default UI elements for something more stylish because they feel a little flat compared to the bouncy, rounded players.
Great work! Congratulations on submitting!
