The puzzles were interesting, but most were far less intuitive than in the first game. The 3x3 pillar puzzle confused me for a good while because there was no feedback on whether each individual goddess's puzzle solution was correct. Also, the final puzzle gauntlet with the crystals was excessive and very unintuitive. I solved the last puzzle with the crystal colors completely by accident.
The story took an unexpected turn in this sequel, and I'm excited to see how it all ends for Alexia!
