Thanks for the feedback! I don't recall Gladion changing his temperament/personality at the end of Sun/Moon, but if he did, that's probably to the detriment of his character. My take on him is a little more mellowed out and self-aware than during the bulk of Gen 7's story, but he's still an edgelord.
Iris shouldn't seem completely clueless after visiting the Tapus, so I probably need to rewrite some dialog. Thanks for the tip!
Music loops and lag should be fixed with the next release. Stay tuned.
