Very clean execution, feels very professional and gameplay is interesting but challenging, however there is a small issue that comes up with how cards are added to the deck and the pointing of special cards. If the player plays a single card and then immediately ends the round, a special card can be added to the deck, this can be done until the only cards left in the deck are special cards at which point the countdown will never decrease while the player can fill their deck with all the most powerful cards repeated infinitely. Outside of this flaw, this is otherwise a really nice title!
