It has good potential, and that's about it. First of all, there's no replayability because there's no end goal and the enemies are very basic.  Second of all, single spells are so OP that it's not worth using other spells along with them. Third, there are only four spells available and even then they have pour balancing as ice can literally fill the whole area with crystals and the enemies just have no chance. And finally, it's very bare bones, the arena can't change, and there is a severe lack of variations. It feels like an unfinished project. It can change if it is developed even more.
