Wow, this was delightful, and truly impressive for a first time game! The animations and visuals look very clean, and the gameplay is clear and compelling. It took me a few runs of my fish dying before I realized that you could spend money to upgrade the tools, though. I would recommend moving the upgrade shop to be with the buying fish store in between 'runs', since there is no way to make money during a fish 'run' there is no reason to open that shop at multiple points during a run. Overall, this is really excellent work. Great job!
