So i feel like you have this whole system planned out in your head and it seems to be pretty extensive for a game jam game and very cool. But the UI is definitely is what limits you here. I didn't even know what was happening in the first minute.
The abilites/moves could have tooltips on hover instead of locking them inside a giant scrollable list
Player and enemy stats could be more juxtaposed, putting them underneath also caused mild confusion in the beggining
and the font. I know its medieval and all. But with this amount of text reading you need a more readable font, definitely.
The fighting system has potential, I can see this being worked into a full game with multiple enemies, upgrades, stages etc. Audio and assets are both really good.
And what a banger title, haha. I don't know, It rolls of the tongue weirdly well.
