Honestly, I think you've made an awesome game. Visually and musically, it's spectacular. The gameplay is super fun, and the jam theme is perfectly implemented. I finished all three levels (not sure if there are more), and I really enjoyed every moment.
If you decide to keep working on this project, I'm sure you'll end up making something truly amazing. Congrats!
Ps: Just some tiny feedback, some times it hard to spot the enemies due to the grass and the UI, and it's easy to take advantage of spamming the attack button.
