I think that during the second fight when one of the opponents should die then the game properly switches to the other target yet he doesn't die.
Although there's no time to make much use of it I like the actual deck of cards you're using in the game with cards making low damage and others making more but requiring a 2 card setup before that. The world map looks cool too.
There could be a sound when you play a card, and maybe even when navigating through the cards.
Thanks for sharing!
