The game is really well done and the graphics look cute. Magical Girl concepts is great, Sailor Moon, Cardcaptor Sakura, and Pretty Cure are really fun inspirations, and recently watched a scene in Split Fiction that is inspired by the Magical Girl transformations.
I did have an error where I was casting more than one spell to defeat the monster, and both spells would disappear when defeating one monster, rather than allow my second spell to keep going. Perhaps adjusting the code will help improve that.
Also, for some reason, my gameplay of the game cuts off a lot of the screen, it's resolution did not match what the instructor's gameplay demonstrated. This may be a "my hardware" issue, but something to look into.
Otherwise, the gameplay feels good, the artwork is good; can definitely be refined further.
