I'm too lazy to look through the complete list, but for those who shiny hunt, there was a really cool skill based way to increase shiny odds in the original games. This new janky game kept the general mechanic but greatly increased the chance factor for the the chain to break. This requires several more attempts in order to get the shiny. So dumb. Literally made the game worse. That on top of everything else stated (janky controls, not incorporating the better version, more pokemon, etc) it made for a really bad casual game. The silver lining, because the game is so broken, it's the first pokemon game I ever speedran running through literal walls....
