I'm not sure if it's possible D: Even only the art itself isn't possible, as it exceeds the limitations of Gameboy hardware.
However, edited versions of the tileset could be made and used for .pocket and GB versions of the game, and the game could be re-made in GB Studio, which is something I've always wanted to do!
But, I don't think the engine will be able to support native exportation to Pocket/GB, I would have to make a similar version of this for GB Studio WHICH, may very well be possible. I will look into it :)
