So cool! I love how all the tracks give such different vibes - 3rd one feels super Minecraft-y, 4th track references Gymnopedie no. 1 by Satie (though i guess those are actually fairly connected, but still), and the 5th track sounds almost like a Zelda track, and yet it all sounds incredibly coherent.
The story behind these tracks is integrated very well into the music - the way it's produced and written, and especially the final track's sound design.
Awesome submission! Great Job!
