Hey Ron. This was pretty fun, but I eventually got completely smashed by a huge wave of enemies. My score was 185. I liked the spin on the tower defense genre and the art and graphical effects were quite good, I also like the font and UI.
I did get a little annoyed at the dialog window not disappearing, it made it hard to see what was coming from the south. I think the progression of difficulty could be a bit smoother, and I also think that the spells/abilities should be introduced 1 at a time to allow players to become familiar with each.
Overall a pretty solid entry, well done.
