Ok so finally finished it and i have to say its a fantastic and charming!
Here are some notes from my playtrough
i would recomend to tweak the final spell renee learns, the short timer just doesnt really make it usefull in combat and i would recomend make naomis cleansing spell and renees shield spell dont need a minigame, mostly beacuse as far as i played there isnt really too much of a change even if you win or lose it still works so i dont think there isnt a point for them
