Yeah, I agree the UI needs work. We were so overwhelmed at trying to get all the mechanics we wanted into this game that we overlooked some of the more basic aspects, like UI and effects.
A video tutorial should come soon, if not a full interactive implementation. The latter just takes a lot of time to build.
We'll have to look at the way we do cards again, because I fully agree that cards and their effects are too hidden.
Thanks for your review! I hope you enjoyed playing our game.
