Neat game - I'm always a sucker for a good soundtrack and good pixel art, and this game delivers extremely well on both fronts! Really liked the dynamic track and how it changed depending on the situation. Execution of the theme was also pretty well done.
Even though I loved the visuals and music, I felt like the gameplay has a lot of potential that wasn't realized. More enemy types and more waves would've been neat, and I think that the way your spell grows could've been tweaked to be a bit better (it felt like no matter how much I upgraded, I was doing the same damage to the wolf enemies). I'd love to see what you do next, because what I saw here has amazing visuals, audio, and great potential.
