I'll try not to repeat any of the feedback below. I think you know what areas the game could be improved in and I applaud you for still pushing through and submitting a project, even with having to juggle school and other obligations.
My feedback would be that for future jams, maybe start on the art and animation last. What you got in was nice, but I liked the movement and wanted to see more bosses and attack patterns, so I think the time you spent creating art could have gone into more of the design and player feedback. Even if everything in the game looked like the main thumbnail image, it would still be a blast to play.
Clicking to fire every time wore me down a bit. I wish I could have just held the button to fire. But a great solo dev entry in the jam. You should be proud.
