Really fun and a great level of polish. The only improvement that I can think of would be to explain the UI a bit more, as I was unsure what that blue bar above the cards did. Hope this gets expanded upon, it's the type of game I could play for hours.
Thanks for the kind words. I'm kicking myself for not thinking about the mini map thing, that makes a lot of sense, maybe even an alarm that shows you the area that they have stopped working.
