Good, but could use some work.
Well, it was a fun game, but it could use some improvements. The sword swing was kind of slow. The sword did very little damage come the later levels, to the point where it was practically useless. Leveling up wouldn't be so painful, if you were able to boost more than just your spells. Stats would be nice to include.
In other news, the graphics were really nice, the gameplay was smooth and it was a challenge. Overall, it looked and played well. With some improvement, it could easily be one of the best defense games on Newgrounds.
