Thanks for playing!
honestly, changing the weapon with the mouse wheel would feel more intuitive than pressing R
I hate scroll wheel for weapon switch so it'll never be default, but you can always rebind your keys.
also, shift is more common for dashing compared to the spacebar
Means you wouldn't be able to mix while dashing, you can't hold CTRL and press shift simultaneously.
fire damage seems very punitive, especially considering how easy it is to press the wrong magic in the heat of the moment and further hurt yourself rather than heal
True, I should make the other damage types more punitive to compensate.
