i understand the basics of the game but i am constantly forced to only discard and pass turn after making it to the third area to corner the villain. i deafeata few goblins/skeletons etc close two of the tutorial areas and upon final area i am forced only to discard and pass. cannot even use any other features. basically stuck. any information on how to avoid this or is it just a bug? ( or ami in the wrong location for this question).
