Hi,
just a few points after playing the game to the 8th badge.
Overall the game is really good so i'll just focus on a few problems.
Walking to pokemon center simulator: around 5th to 6th badge, the difficulty is clearly higher, which is good overall, but the need to heal the team is way too important, leading to too much time spent to go back to heal pokemon.
Pelistorm: its signature move "the world" is bugged, if you kill a pokemon with the 2nd attack, it has a 3rd turn of no move for the opponent. Overall I find this attack way too powerful, and the bug is making it even worth.
Nullifiers: another broken mechanics, I understand the idea to use this to balance the game toward the AI, but feels unfair most of the time. Unlimited immunity is way too powerful. At the bare minimum make it so it can be seen by the player when an opponent pokemon use it. Curently it pretty much kills one of your pokemon each time you face one.
EVs: the player needs a better way to farm EV, like trainers we can pay to raise particular EVs. There is already this system for exp with ingeneers, implementing something similar with raised EVs for each fight would be a good way to make things easier. Without this, adding new pokemon to the team late game make them way too weak, and changing pokemon is something frequent in a game that long (the minimum being adding the 2nd starter to the team).
Sylen city: this part of the game was way too long, between the main quest and secondary ones, I didn't like this part of the game, too much time spent not actually playing pokemon (battles).
Input bug: I don't know why but when I'm in the menu, the "Esc" button to go back to the game isn't working properly and I need to press it multiple time for the game to register it.
No ingeneer in the town of the last badge: make it a real pain to level anything at this point of the game. Wild pokemon are too low to again any exp on them. Don't know what to do at this point.
Despite thos few criticism, thank you for the game, it's really good!
