Great tutorial! loved the style

Good game concept but needs style! you can disguise gaining and losing different mana types as the result of some attack or spell in the cards, that way it adds some imagination to whats going on in the battle, the art in the tutorial is very cute you should use that for the game elements too!

That's what game jams are for! To make a great new game design and test it! I love that you focused mainly on mechanics and rest is just minimalistically stylish. The game plays and feels really good and imho it has one of the best, creative, innovative and well defined mechanics out there

Interesting.
