I love the art style and pictures of the fish! I caught a huge rainbow trout and some large mouth bass. I wish there was a little bit more to do other than wait and click, but the fact is -- this is a fairly accurate fishing simulation! haha. you really only need to cast the line, wait and reel. Maybe if you added aspects of strategy to find an area where to fish, then set the hook (as you have right now), then include another minigame for reeling it in. Most fishing games I've played also have the fun of collecting lures, etc. If you're an artist, that would be a great place to showcase your style in the design of the flies.
Great work! Congratulations on submitting!
