Alrighty, first off, the speech speed is extremely slow, I would ask that you install a text speed button selection, or maybe text boxes in which you click to further the text.
I would also ask that you install a mute button, though I think you added a reasonable level for the audio, so for that I thank you.
I suggest removing or making the buildings smaller, as the obstruct you view, especially when you go to look for the special hemp. I would also suggest that the sliding ground be quicker, and sound a little more consistent, as the loop is really painful to the ears.
My major gripe with this game, is the ending. Or what seems like the ending, I really dislike that it ends with a picture of hemp, as it doesn't feel rewarding to do that tedious task to end with a hemp let alone not seeing how it helps the villagers.
I would much prefer an ending where you see the villagers cross the earth that you stitched, be it that they're escaping an action by mother earth, or something of the sorts, as then you feel like you were truly helpful and it would at least justify your actions.
Overall, nice graphic style, somewhat ok gameplay, the story is really appreciated (cause so many games don't have good stories), music is at good volume but the text speed and sound effects are somewhat annoying.
