1, The animation is somewhat too slow. It could be speeded up a little.
2, When the capture is 100% secure (e.g. you need to roll one point with one dice using enhachements) could be done without rolling the dice.
3, The dragon weapon I miss. It is when you have a strike of 3 cards in the same color and then you need to roll 6 points with 2 dice to capture any dragon.
4, Strategic variant I miss, with 2 open adventurers to choose from alternatively to the pile.
5, The field for the dice could be smaller (mobile version)
