Did you ever test your game? It's buggy as hell, especially the unit movement and spell selection.. about 30 times now, the game gets stuck on casting one spell.. I can only cast that spell and click the buttons.
Pros: Fun, newish concept
Cons: Bad UI, towers typically only move a maximum of two towers. Sometimes they will not follow a two tower route at all.
Repetitive
Poorly balanced
Lack of content
