hey there! this is a solid attempt. from a gameplay perspective there's a few things i would call your attention to. for one, the shark you control has very loose controls, which doesn't feel good in a game where you need to be accurate. the projectiles you shoot are also very small, and combined with the previous it feels very difficult to aim. finally, when enemies get shot there's no impact, they just disappear without a trace, which makes it feel dissatisfying or even confusing to take them down.
good luck in the future! i hope you keep it up
