Well, I just finished the Elite Four, I have to say this for me has become the definitive version of FRLG by far. Not only this game solves nearly all the issues that kept me away from going back to Kanto, it actually does even more than I expected.
Simply amazing upgrade. Loved almost everything about it, the QoL changes, proper update to Gen VII movesets and abilities, the move animations, proper optimization that many fan games are missing, much appreciated increased Pokémon variety, reasonable increase in difficulty, no fanmade type or move changes, and so on. It worked so smoothly from start to end with no bugs or crashes.
My biggest gripe was that the battle back sprites look too tiny, I've seen this issue in other fan games as well so I suppose it could be intentional, but I personally decided to upscale the back sprites of my team using Photoshop. One thing I believe could improve the game is adding at least a few more Gen 5-8 Pokémon available in Kanto, not many of course (to avoid bloating the wild areas too much) maybe just one new species for each area to increase the availability of post Gen 4 Pokémon a little, since (except for Meltan) you can only get those pretty late in the game after Cinnabar gym.
Idk if this project is still active but seriously thanks for this, really solid and amazing work.
