Very unique idea and great take on wildcards.
Look very nice and music fits well.
Reminded me a bit of Black and White :). I had fun figuring out how to play and trying to manipulate agents actions. I tried using rock and killed the knight (didn't expect that :D ) and decided not to use rocks again, but then came up with idea to spam rocks around spawn point - this made agent confused, it ran forward a bit, got stuck and panicked :) I would consider this a nice feature of the game rules, figuring out a way to abuse the agent and using it - it gave me that "Aha!" moment.
Presentation in the scrying orb is very nice, but at least for me (I might be in minority) it would be more intuitive to have moving camera (RMB) reversed - I imagined it as pushing or pulling at the orb, kind of like swiping on a smartphone screen. But this way I guess also makes sense, you are pointing to the orb in which direction it should go.
Not sure if spells costs are shown somewhere? At least I didn't notice any difference and didn't know if I could cast spell or not. Some more information and extra feedback there would help.
Great entry!
