I had a hard laugh because of the hitting sound effects.
Now being serious:
The game overall is fine, I mean, it isn't bad, but the idea isn't really that original, and it feels like an Space Invaders but you have to reload.
I like the recharging mechanic, it kinda makes it different from said game. However, the ufo and the fish could be replaced with most things and the game wouldn't be that different.
What makes me like your game, is that you wanted to make it funny-looking and with the sound effects and art style, it's really funny to play and you get a smile on your face, that, and the effort you put on it, make me like it some more. However, I think these jams are about making original content, not just adding the elements / limitations as an afterthought, but making them integrated in your game for real.
Still, I see you really like doing these games, so don't feel bad! This is just a comment pointing out some things to try to help you improve, but you can ignore them if you want. Feel free to do what you like the most, just wanted to give an opinion about this.
Farewell.
