I finished the 2022 version of Azure Horizons, I like the new content. I did however, find some errors and I have some suggestions.
-In Route 801, you can walkthrough the ledge from the south.
-You can't read the signpost outside of the old lady's house in Gordian Town, it's the same with the signpost near the Route Gate in Route 806.
-In Morphic Tunnel, you can't cross the bridge underneath Lass Dawn, there is a missing item ball where you cross the bridge, Also, there is a missing Youngster to the bottom right of the cave.
-The ferry in Azure City is incorrectly called the S.S. Aurora, when you arrive on Faraway Island it has the overworld of the wrong ferry.
-Bug Maniac Brett has a Gyarados, he's supposed to have a Volbeat.
-The northern half of Route 807 needs more trainer battles and maybe some items. You could add the leftover seven from Kanto Route 13, seeing where it appears to be based on.
-I think the ruin in Route 811 should be named Desert Ruin and have Pokemon like Sandshrew, Trapinch, and Baltoy, instead of Slugma.
- There are NPCs who still mention Tanya as the gym leader and not Grant.
-Crevasse City has a weird looking tree border in the southern half.
-You can see the walls of the opposite floor of Crevasse Gym, when on the first floor or basement.
-Routes 816 through 819 should be blocked off until you have the sixth badge, also the trainers should be higher leveled.
-Routes 820 through 822 should be blocked off until you have seven badges. You should only be able to explore the beach part of Route 822 at the time. Again, the trainers should be higher leveled.
-Route 826 should be blocked off until you have all eight badges.
-Route 818 should have more trainer battles seeing how big it is, Route 824 should also have trainer battles and even some items.
-The male Swimmer on Route 813 should have a Wailmer, seeing how it doesn't evolve until level 40.
-You can't obtain the item ball in Lake Aurora on the western waterfall.
-The cave in Lake Aurora is misspelled as Lake Aurola.
-Zephyr League is misspelled as Zephar League, also the signpost statues still say it's Indigo Plateau.
-The trainers in Polaris Gym still act like it's an electric gym, like Beauty Kana for example.
-The Exp. Share should be obtainable early, the latest I can find it was in Polaris Market.
-The NPCs in the Route 825 Poke Center have unedited dialogue, the Gentleman even mentions Team Rocket.
-You can't get Staraptor from the Camper in Polaris City.
-Ace Trainer Nikki on Route 826 should use the Pokemon Ruby and Sapphire Ace Trainer sprite and not the Fire Red one.
-The male Ace Trainer in Route 826 battles as Aroma Lady Violet, complete with the same Bulbasaur team.
-Both the desert of Mt. Origin and ice cave part of Mt. Origin should have more trainer battles. That and the ladder leading to the desert cave of Mt. Origin is the same up ladder in the ice cave portion and not a down ladder.
-The S.S. Aurora could be used as an S.S. Tidal like ferry on the way to the islands you can take it to. It could also the unused S.S. Anne trainer battles and the unused S.S. Tidal maps in the Fire Red data. This would give some thing else to do in the post game besides the gym leader rematches and additional Pokemon to catch. That, and you could get the Leftovers item, I don't know if it's obtainable.
-Polaris Gym should be Dark like Dewford Gym, except you can't use Flash as it's the final gym. Victory Road should also be dark, but this time require Flash, along with the new cave in Morphic Tunnel.
-Another thing that I need to mention is that you can't Fly to Scarlet Town.
-In between Gneiss Town and Windward Forest should be Route 809 as the game skips from Route 808 to 810. You could use Green Path as the main location since it has a forest entrance.
-Pokemon names need to be decapitalized, I know that was one of the creators intentions.
-There's a Pokemon Ranger in Victory Road with a Shroomish, he should have a Breloom instead.
