This looks cool. I'll update my comment once I've played the game a bit.
EDIT: Played the game, and I love it! I think that this could really go places, and I only noticed a few things I'd love to see:
-May have just been my ignorance, but I didn't notice a save option during the introduction arc. If there isn't one, I feel that would be a cool addition.
-I'd like to see more map options for the one-device mode, if possible
-Maybe other card effects than Stun? Like a poison-style damage over time effect, or a stun that only affects movement or attacking?
Overall though, I LOVE this game, and hope it gets more traction and exposure. 10/10
