A good stab for a first game, but if it isn't, there are some things wrong with it that could be fixed. There is no real end, which means that you can go into the negative score range without losing. The end should either be at a negative score, a certain amount of time, or a set amount of fish. Also, the eagle will sometimes miss fish that are swimming right at the surface. Its legs go a bit deeper than the fish, but don't catch it. This problem doesn't occur every time, however.
My favorite part had to be the music. It seemed like a mash-up of Sonic and Mario (mostly the prior), both of which, like this, are excellent game styles.
