Yes I agrea the turn transition could be a bit faster.
Its fine once or twice but on a full combat it gets old... I learned my lesson there.
As for the mana its curious as I put some big blue mana icon that i felt were obvious.
You start with 0 mana though which maybe was the confusion.
From 1 to 3 mana you should have the icon showing up and a + sign if you have more than 3 mana
Or maybe that is what you mean. Above 3 mana you have no way to tell how much you have.
I just realize that writing those lines.
Very easy to fix, just didn't thought of it, my bad.
I'm glad you played the game, I'll try yours in a bit :)
