Thank you for the suggestions! I've definitely thought of (1) myself and that you should be asked to swap and be given some space to test out your new ability. It really was a last minute addition, hence why only a few of the pearls were implemented. As for (2) it's caused by the fact that Snail and Noctua have a "null" pearl because I didn't have time to add two more pearls, thus failing the completion check. I hope to patch these things as soon as the voting period is over! Let me know if you have any suggestions for pearl abilities you think could work.
