I'm going to be generous.
I like games that try to keep things simple, often giving them a better score. This game has gotten my 10/10 for that reason, but even without that it's great.
The music fit well, frantic in a way. Always a nice thing.
The spells were basic and easy to understand, the enemies easy to tell apart (the green on the knights and the blueish tint of the undead things made it easy to tell what was in front of you, hopefully you remember what spell to use before you run into it!)
The rocks added a lot of fun, something else to be aware of, and it was generous, I was sure I would get hit sometimes, but came out well. This is good, you can't concentrate on jumping at the exact time while reflecting a warlock attack and dispeling an undead. The jumping and ducking system was very good, something I like a lot in a game, something that many mess up on.
So, it's fast, pretty good looking, decent gameplay, eh~ story, and it's all around fun. It doesn't need to be incredible to appease me, just simple and smart, and you did great on both.
