Hello, these are certainly not of major importance and they very well may have been brought up before, but if they were ever to be implemented it would be greatly appreciated, so I thought I'd just throw them out there anyway in case any other players feel the same.
1st is the mount music. I love the music in the game, especially since it isn't as limited as it is on the cartridge games due to the limited size available on cartridges. Due to the repetitive nature of Pokemon, it also helps to retain interest. I've noticed that every time I jump on my mount that I purchased, it switches to the same song, which becomes incredibly repetitive and discourages me using it. If there could ever be a setting added to the menus in a later version to disable this that would be great. A simpler solution would probably be to disable it all together and just have it activate the same music per region as when you're walking - I don't think the mount music is particularly a huge loss anyway.
2nd is the battle music. It would be great to have all the correct music from the different regions. I vauely remember seeing this mentioned in the chat as being due to some sort of copyright issue (although I'm not about this and I wouldn't have thought it would have mattered since it's non-profit anyway). Also, it would be nice to have a pool of different battle music to make it a bit more interesting. There are some great artists who make Pokemon remixes such as Glitchxcity who I think would probably be happy to allow the use of their music provided credit was given since it's non-profit and it would help spread awareness of them.
3rd is the size of the in game sprites, I'm not sure how problematic it would be to make them the correct size, and the larger ones would inevitably clip into walls etc, but I think it would still be better overall than having a Snorlax for example being smaller than the player. I remember seeing Golurk in-game that was huge and around the correct size so I was wondering why this was the only large pokemon (roughly) close to its regular size.
I'm sure you have more important priorities to address before this, such as abilities that are not yet programmed, and ironing out any bugs with Sinnoh, but if you ever find the time to look at these, it would be greatly appreciated. Thank you for creating and maintaining such a great game out of your own time. :Grin:
