Great game, I just finished the first gym, (I think the badge is missing, not sure) and I would like to share my thoughts.
First, leaving aside bug pokemons (they have weird expressions) all pokemons and trainers look great, the girl in the museum at Copperpath it's great, and I would love to see more characters have their close image when talking to them like her.
Second, spawn rate is wayyyyyyyy too high, when a battle occurs within the first tile of grass you touch is something common, there's a problem.
and Third, the starting city, it feels too big and disorientating, mostly because of the close camera. I'm sure you have plans for the city, so instead of scaling it down, I think there should be more paths for the player to take to reach what they need. Also, ignore me if I'm wrong, but I didn't find any clue of where the lab to get my starter was, as someone who just downloaded the game, alongside the big city hard to traverse, it was really discouraging.
Lastly, the gym leader felt way too hard, not because it was unfair, I'm not really a pokemon player so I don't have a good opinion on that, but because it was a big spike in difficulty related to any other combat, at the end I just used all 15 candy in my Ralts and cheese it.
and before I forget, maybe a Gallery? I have never seen a pokemon parody with a gallery, maybe there's a why, but Like I said I used candy in my Ralts so I ended up with Kirlia, and now I can't see the scene.
Overall, It was great, I hope you can finish this project, and deliver an splendid game, so far It is looking great.
