Nice idea, wish I could see an animation of the mage casting spells and enemy blood damage effects. Didn't need to upgrade anything cause the enemies were easy (cause I'm that good of course). Would be cool to see different types of enemies. Like If there was a flying enemy you wouldn't be able to cast the fire spell because it only works on the ground. So different spells are effective on different enemies. And then if you spawn lots of them, it could be very chaotic. Good job, keep at it!
