The illustrations are absolutely beautiful, and the modeled world its self is really pretty, great job on the art! The gameplay loop was actually pretty fun, even if it was very simple. I enjoyed the feel of racing against the tide but it did get old pretty quickly. The song is nice too. One improvement I would suggest would be some sort of upgrade system so that collecting all the beach treasures has more of a purpose to it. Overall I think you have a really solid foundation for a game with some gorgeous artwork, cool entry!
