I love deckbuilding games. I had fun playing this.
Great music choices and very nicely polished game!
While playing the game I was not really sure what the two mechanics were. (I think building your deck and battling)
I think it could be very cool to extend this game with more enemies + artifacts + upgrading cards or you could try to do something crazy and be super creative and give your own spin to the deckbuilder.
I wanted to see how I ranked with the other players but I think the leaderboard is not working yet or someone hacked it.
