>>26721786Not that anon but I finished the 4th gym recently as well. I'm quite pleased with the difficulty personally I feel like you've done a good job of making boss trainers challenging without over-leveling them.
I do have two glitches to note though. Firstly when I go into Graphite City from the west after the 4th gym I get stuck as soon as I leave the building. I also have acquired permanent rain from the 4th gym leader battle it persists across routes and through buildings I fear for the children of this land and dread the day when I am hailed as rain god.
