The sprites are really nice, game feels pretty polished and mechanics are fun.
I liked memorizing the spell combos, and it felt good to unlock new spells. I think the game could benefit a lot from a few more SFX. Things like a different sound for entering a direction, completing the spell, and failing for some instant feedback would make the spell input more satisfying, since it's the main way to interact with the game.
Also a few bugs I found were the poison shield and frost coat seemed to stop taking input in the middle of the combo? As well as gamer difficulty didn't seem to be able to trigger the direction UI anymore, but dunno if it's just on my end.
Overall, I enjoyed my time playing this. Great work!
