Made a little game prototype during the holiday break… anyone up for providing feedback for card battler mechanics?

You start a round with the option to burn a card. Burning a card earns a star. Stars are used to play cards. Burned cards are removed from the deck.

After burning a card (or not), you can play cards. Drag attacks onto monsters to attack them or shields onto the hero to bock attacks.

At the start of each round you receive a star for each card you previously burned.
