Art style was very cute and drew me in immediately!
Ended up getting soft locked in a situation where I had no energy and no coins and every card required energy. I'd have some kind of check to see if the player has the chance to make a choice and end the game if they can't, or make it so that there's always 1 card in the hand that costs 0 energy so they always have an option even if it's not great.
This definitely has potential to expand and grow!
