I'm glad you managed to finish the game even after struggling with the controls!
To be honest i thought the same about the controls, the Arrow Keys do work for movement and incantation too, at first the game controls were designed like you said but a friend of mine that uses a 60% keyboard complained about not being able to cast spells so i had to change controls a bit. I forgot to mention it on the game so people could choose between arrows and WASD, stuff to add in the future for sure. Thanks for the feedback!
