Wow the art with the 2 samurai is amazing but i think the ui is a bit massive haha.
With the fighting, i just matched the element/armor they had on my defence and used something diff on offense if possible and seemed to have pretty decisively won against all the enemies i fought, but i ended up stopping in the middle of the game as i didnt know if it was just endless and the loop decision making seemed a bit too simple after awhile.
I really liked how you ended up taking their armor but idk if that had much of an effect on the stats or not.
i could def see something like this being more interesting with more rpg mechanics added in tho. great work of course!
