really fun to play! super impressed with the visuals and the concept, very cool! felt really satisfying to actually learn the spells and then type them out lightning fast. the music was really nice, and I like how the key songs link in to the opening melody of the songs that play after the level ends. i also like how the game auto-aims for you at the nearest target. super helpful!
only criticism i would add is that the inability to use a key after rage mode makes it more of a hindrance than a help, because after rage mode i basically have no health and can't use many of my spells(especially the healing spell). i imagine this was added to debuff the healing spell and prevent the player from healing endlessly, but maybe consider using a cool-down on the healing spell instead. also the movement control could be a bit smoother.
overall, great job!
