I love the ambient atmosphere of these tracks. They truly do open the mind to imagine a world you've never seen before. I would listen to the second track "The Mechanic" while writing a fantasy story, It really sparks the imagination for me! I can clearly see the vision of people living inside a piano and this being a game that can exist. The sonic bed you make with the piano mixed with the textural sounds do a lot to create that feel you're going for. If you were to continue the score I'd even suggest adding a bit of reverb to the chiptune harmonica type instrument. Overall this is a really fun piece!
