Learned how to move, collected guns, used them to kill evil cards, then collected some more guns and used those instead to kill any evil cards that escaped my bullets on my first watch.
That until I found a strange portal which captured my strength, and saved the cards from my wrath..
..but hey, at least that UI person told me that I won, so that's something!
Pretty cool gameplay overall -- simple but fun!
Just wanted to share that recently discovered that one thing that can add a lot of fun for the player in this kind of games is right click to roll, would totally recommend for your next game if it's similar :P
