Congrats on finishing and turning in your first jam game! Great job!  The controls are smooth and responsive, and I really like the sword swing animation.  Also it is cool how the purple boss has different attacks~  For tip, try adding some Unity particles to the projectiles.  You can also instantiate them when you hit the boss for some juicy hits.  Again, great job~  Please check out https://neatgames.itch.io/only-one-arrow  if you have free time.

I had fun with this short game. I think especially for a first jam game made in 48 hours it's pretty good. Adding more indication on your enemies attacks would make more even challenged boss battle.
