Man, that was a nice way to implement a puzzle game with this theme! The game looks very nice! The art style is consistent throughout the game and I like it! The music fits your puzzle take on the theme.
Well done sir!
Ah, I was worried people would find the music not calm enough, thanks! :) Usually, developers often go for soothing music for such a game, as you can see in other ones, such as DOS and especially the (very sweet) Marimbla.
I wanted to give a feel of mysterious adventure and progression, through both the music and the scenery, which I think is another specific feature of the game (as far as I have seen).
