I've just finished this game. This game may be years old, but I'd still like to point out my main issues with the game. Feel free to let me know of any reasonings for these decisions:
-Levels too high and unreasonable. Level grinding would be a real pain without infinite exp cheats (use Crystal or Platinum as reference for better level sets).
-Late game normal trainers have more than 2 healing items. Why? Just give 1 to late game normal trainers, 2 for Antagonists/Gym Leaders, 4 for Elite 4/Challenge Guards, 6 for Champion/Challenge Master.
-Boss' aces unreasonable (e.g. 1st gym leader has Porygon-Z)...why?
-Learnsets/movesets inaccurate (e.g. Scraggy doesn't learn Low Kick at lv. 1, Magnezone has Iron Tail, Absol has Barrier)
-Western Tyron rushed? I am unable to fly to southern-western towns including Challenge Bridge
-Character designs questionable: why swords?
-map too large/overextended; too much unnecessary space/space with nothing or just tall grass
-Why dragon/fighting Axew line? Makes no sense
-Music: unbalanced. There are odd 8-bit like tunes that overpower the overall themes, making them difficult to listen to (e.g. Trainer Battle theme).
-Event tile placement to get Dive is questionable. Why not disable Escape Rope/Dig use inside the Storage Room and put the event tile in front of the front entrance?
-Sky Tunnel: almost copy-pasted from Victory Road (Hoenn) 1F-B1F. Not so much a major issue, but still feels lazy.
-Pokemon sprites like Lopunny and Victini (back sprite) (Drapion from Mega Power is another good example) are squished. Again, not a major issue, but still unsettling nonetheless.
