Pretty simple, but it's fun
The art is also fine, but I think it could have had a bit more of animation. And that cat has truly seem things x)
I also like the music, but I kinda wish it was a little longer as well, but nothing too serious anyway.
Some actual nitpicks I have here is that I think the fish spawns should be telegraphed somehow, the way it is now you kinda have to rely on luck for a fish to appear near you or you most likely won't get to it where it appears on time (or you do like me and stay most of the time on the middle of the screen lol). Also, the currents on the top and bottom of the river are almost invisible, I accidentaly got on them way too often.
Anyway, behold my gamer skills
