This archetype is really great! It's not very playable, but it's really thought provoking. I love your material design within the valley of inaccessibility, it's beautiful and coincides with your zhu ti. The sound effects section is also wonderful, the player can easily understand what you are trying to convey through the sound effects.
In terms of this project I think you've done enough, but if thinking about the difference between these platforms, something other than textures could be added. For example, in the valley of the insgram you can go all the way down and collect heart symbols. Give the player some roadblocks or simple quests to enhance their experience in the valley.
