Thanks for the play and honest feedback! I didn't realize it was either of those as you can avoid and run past most of the enemies. If you try to kill everything, I can definitely see where you are coming from. It's my first game jam, so I'll keep this in mind for the next one.
I would have loved to add more enemy variety, sprite animation, and varied AI especially for the Boss fight. However being my first game jam, I simply ran out of time. I learned a lot on this project though, so that should help me better manage my time in the future.
