I like card games; I don't like back-and-forth defence games. With a rework of the gameplay, the soldiers, resources, enchantments, etc. could function well as either a card game like Elements or as a turn-based strategy game.
Manipulation direction controls are a bit fiddly; must be even worse if someone's using a laptop trackpad. I'd like to be able to just click the direction I want to move a piece in and have it remember that while I move the mouse.
