I think visually you've really nailed the look of this - it looks great. I liked the different skills and the variability this gave me in designing a custom build. I liked going with 3 x circling orbs (as far as I got, not sure if you could do more!) and lightning. It looks like you might be considering this for a broader release so it would be good to maybe get a bit more detail going on the enemies. I really appreciate the use of an array of sounds for your hover sounds - thats a really cool touch that sometimes goes unappreciated. Great job - I'm going to go play another round.
