Really great game for the jam. I will say a couple of things for feedback -
The attack itself felt a bit clunky with having to be both stationary and very close to the enemy to use it
It felt a bit bad getting hit multiple times without getting any invincibility
I know I saw this in someone else's comment, but coyote time would be good at helping the platforming feel a bit better
Also potentially the camera being a bit lower, it felt like I couldn't really see what was below me until it was too late
With all that said, the art was amazing, I was really impressed with the health animation, and the backtracking once you had the right skills felt great.
