I'm amazed by how polished every single aspect of your game was—I feel like your experience really shows. (I made my first ever submission to the bullet hell jam, so I'd love to get your thoughts on it.) I especially like the way the arrows stick in you as you get hit.
The only thing odd I found was that sometimes enemies could get themselves stuck in walls (attached a pic), which was a problem if they went far enough in that I could no longer hit them.
The nice variety of enemies stopped the combat from ever getting too repetitive. All The enemies attack patterns all felt very fair and the game gave me a nice power fantasy.
I really like how you locked a small bit of narrative behind the Star system. It seems like such a great way to encourage people to try replaying levels... it worked on me at least :)
