Wow, it is definitely very original and the initial idea is a valid one, even though it's not easy to achieve. The mix is very clean and balanced, and the choice of instruments as well. I might have given a bit more prominence to a central musical theme because in a video game soundtrack, it's important as it highlights and emphasizes the qualities/emotions of your protagonist. I recommend writing a more detailed story because it gives even more value to your music! That said, I think your work is very interesting, well done! (Childhood Well is for sure my favorite... Wonderfull textures and fit very well as a theme in a videogame, or also as music for exploration).
