This was such a fun play! I'd love to see more precise enemy and ally AI (they kinda just wander around aimlessly) and some more visual differentiation between the sides. I think having something to do while your energy recharges would be very helpful to keep the player engaged as you keep playing, or maybe even add an opposing God that uses their own spells on you and adds another layer of complexity?
Regardless though, this is REALLY polished, and quite a blast. I love the greek theming, music, and SFX, and the gameplay loop is really nice.
Great work!
