Hey, I liked your game and especially the fact it's already playable, yet still simplistic. I'm also doing a card game and trying to come up with the design ideas for it, but don't have a playable demo.
But right now I'm still thinking about ways of how to create cards. I've ended up with developing a web-based tool for generating cards. Maybe this tool can be somehow integrated with your asset? I'm still a Unity-newbie, but I'm already tryint to recreate my logic in Unity.
It would be gratefull if you can take a look at my generator and provide any kind of feedback. I really respect your work and it would be very cool. Cheers!
