Thanks for asking! Actually I'm working on the idea and aestethics before starting the whole thing.
I'd like to have a good part of the tileset and fakes done before starting to make maps and such. Also, I finally decided to use Pokémon Essentials for this one, because a hack would make my ideas a lot complicated (at least for me) and would prive me from the extra space the game needs.
Any support would be really appreciated!
