The wild cards are only there because they have to be present in the game to get points for it in the Gain Jam judging, as far as I understand it. As for the cutscenes, 2 of them are for the good score, 1 is the 'bad end' in the castle, and one is just the intro.
Glad you enjoyed it, apologies for the hiccups, this one sort of ended up as a mad dash to get it playable by the finish line, haha
