I like this game. It's fun to learn how to use the different spells, what they are good for and to try and utilize the current spell before it switches again.
Maybe the lightning storm is a bit too much out of control for my tastes, but it didn't bother me much.
Also the level numbers are going crazy I was suprised to see Level 174 after Levels 1 and 2, a fun little surprise. :D
Graphics and sounds are nothing too fancy but completely servicable for this game.
All in all pretty fun experience.
