I adore this! I love that your goal isn't to hit the enemy but to bring bananas to the people. It's a light bullet hell—a banana hell. One of my own making when I whiff and my own banana comes flying back at my face. My heart is in the right place but my aim is very bad, hahah.
Displaying the UI elements right there in the background / on the actual ground is a very clever touch, sound effects are solid, music is fantastic—that dirty jazz is somehow, hilariously, perfectly fitting.
All in all, a great game. Well done.
