I enjoyed it thoroughly !
Now, I think the hitbox of the sworswing should be bigger, you really need to glue to the projectiles to deflect them. Still, the hitbox linger long, so it wasn't a horrible issue.
I like the shield mechanic, it's a shame you didn't use it. Enemies shield themselves and very rarely give you the element to break it. Most of the time I was just waiting for the shield to disappear because of it.
I wish they were a bit of music too.
It's a cool entry and I had fun playing it, also i want to thank you for not making the game hard and punishing !
