Great game! This is literally my first experience with jams, and I love the work done on the visuals and the underlying design!
The parry/attack mechanics surprised me, and I think it's a good idea for development. The enemies are beautifully designed, and their variety keeps things interesting, but I'd add some unique animations and more dynamism.
And I equipped all the perks after battles in one slot and seemed completely invulnerable, so I think the balance needs some work.
And the first boss at one point just let me beat him up, hahaha, I don't know why!
Good luck with the development, you've made a great game!
