Thank you for answering, it's most definitely my pc's fault: i have a slow one and it crashes on every map as i try to save lmao. As for the skip mechanic, i was thinking you could add a sandbox mode where the player has full control over the cards, this way the "normal" mode can still be played under the card's influence without impacting on balance, keeping the two things in a separate way that lets you develop the game with more freedom.
