Really impressive effort. Felt a very complete game. Thought the gameplay was fun and interesting and really liked the tool system. Though I'm not 100% sure about the chanting mechanic. I ended up writing down a cheat sheet that mapped a given spell to the numbers I needed to press. I think with the time pressure, trying to remember spells is quite challenging, particularly if you don't have good short term memory. Perhaps with a more gradual tutorialization you'd be able to internalize the sequences.
