Loved the sound and graphics, and the game mechanics worked perfectly. Was there something I was supposed to do with the fish? Or a goal? As I was playing it felt like it would just go on forever. I think setting up at the beginning some sort of end goal (catch x number of fish, catch the Great White Sturgeon, etc...) it would have kept me playing for longer.
Otherwise, solid gameplay. Certainly the start of a great game.
Thanks!
Good luck with the Jam.
