I'm doing a second run of the game as I speak because I pretty much beat the whole game on the first run and enjoyed it every step of the way, no questions asked. However, there were a few things I noticed that I feel kinda took away the experience a very tiny bit, but I still wanted to point out:
* Rock Tunnel has a demake of the Kalos Power Plant music as its theme, which I found a bit off for some reason. Yes, the Rock Tunnel is close to the Power Plant, and you even find the Lode Stone to evolve Magneton with in there, but I felt like it didn't fit the theme enough. To be honest, I thought the generic Kanto cave theme fit it better than what was used in this hack.
* Same goes for the Safari Zone in Kanto, where it uses a demake of a Sinnoh route music (I think it's 210?) as its theme. Again, it felt off. I don't know why. The Great Marsh theme from the same game definitely could've fit it way better, if it exists.
* I know your reasoning for omitting Stantler from this hack (he sux), but, like you did with Ledian, Persian, and the like, you could've easily changed Stantler's typing to Normal/Psychic, and give him a buff to his stats, you know, make him a better Girafarig or sometheing. Just a thought.
* The themes for both PokeWalker routes both don't sound right. For instance, Yellow Forest's Route 210 demake feels very unfinished, and the Quiet Cave, while benefitting from no music at the moment (Get it? QUIET cave? :laugh-squinted:), I still feel like there should at least be a tiny bit of white noise to up the ante of the cave, y'know? Just my thoughts.
That should be all the nitpicking out of the way; apart from these concerns, this is one of the best Pokemon hacks I've ever played (apart from Prism, but everyone says that nowadays :wink-right-eye:), and I hope you keep up the good work!
