This is really cute, albeit a bit simple, good work!
I like the use of the theme that you did and your use of the assets you had, though I will say it was a bit easy to just camp out at the top of the screen and get the bags before they hit any fish. The sharks were a great touch to help fix that issue but didn't do much when they weren't near the top themselves.
I think for your next project you should start looking into easing functions for some of the movement/animations, just to add a bit of a kick to the player and/or other objects on screen. You can find a good reference for the math right here: https://easings.net/#
