The art is quite nice. I love the waves cleaning up the written marks on the ground to signify a start of a new round. I also love the sound effects you picked. I think it works well with your game. I guess one thing I can critique is the difference in size between the tiki-taki-toei board and sea waves. I feel like the sea should be at the same zoom view as the board, you know what I mean. Other than that, good job overall.
