I like the creativity in the gameplay here. I like the music you've got here. I think it should go longer before it loops, since the player can spend some time thinking. Is there a way to revisit the rules after they're initially presented without refreshing the whole game? I saw something about rotation, but I couldn't figure out how. I think the wave aspect was a unique take on the theme. I would love to see something more visual indicating the wave other than the blinking of the tiles. Maybe a moving vertical line (since it's a graph, I'm thinking of the vertical line test)? Or something bigger that flashes?
