Gets boring real fast - every mission follows exactly the same pattern: Upgrade your production thingies and ctrl+click your bays to win. Has potential, but currently it's a one-mission game :/
1) No challenge - no balance between units and they don't feel special. 2) 'Castle' layout doesn't matter squat - position should matter and the building part of the game could be more complex (eg. archers shoot best from the frontmost of a row [no obstacles] while mages could wrap a tower around them that got more powerful the higher it was (the more mages sequentially from the ground in the same column). 3) All the maps are essentially the same and the same tactic owns them all (make a few melees to keep enemies at bay long enough to build/upgrade archers that own everything at the edge of the screen) so the game gets boring real fast, it feels like I'm playing the same level over and over again. We need a story and changing and more complex battleground.
