Criticism -
The music was a little bland for what it was and got repetitive extremely fast. Also, the most powerful rock and ice spells still felt fairly sluggish to use, making them not as fun to mess with as the lightning and fire spells. I also like the element damage system, but don't feel like it came into too much play as a lot of the game was shoot enemies fast.
Support -
The enemy types and attacks were extremely interesting and I liked how they mimicked the user spells. The concept of less spells = more powerful is also an interesting spin on the theme as it breaks away from the ideas of health and money being less or more.
