This is a cool game! I liked the music and the tornado ability feels cool to destroy enemies with.
Two pieces of feedback I have is the mouse sensitivity is too high, it would be great to have as a setting, and there isn't much feedback when the player takes damage. The health bar ticks down, but it would be good to have an animation, sound effect, or some hit pause when the player takes damage. You have the animation, particle effect, and sound already for when the player attacks and damages enemies, just need to apply some of that to the player taking damage! If you apply some Hit pause to enemies taking damage and make them flash white or red for a moment it'll make the tornado ability feel really meaty!
Awesome job!
