I like the concept here. And there's a lot of enemy variety too. But I think the biggest issue you need to tackle moving foward is feedback. It's hard to tell when a spell works or when it's ready at an instant (the bars help, but not enough). It's also hard to tell the difference between your soldiers and enemy soldiers. Granted, you clearly didn't have time for sound and sound is a huge part of feedback, so it is very understandable. Otherwise, fun concept and fun gameplay. What more could you ask for?
