Hi!
About the music — make sure that "Play on Awake" is checked, and that you press the save button (the one with the save icon), or F5, or CTRL+S (all of these are save options, they do the same thing) before entering Play mode.
As for the point filtering on skin sprites — when I first added the ability to modify the player's skins, I didn’t have enough knowledge, since I was learning as I went. Now, in the "Map Editor" update, NPCs use point filtering, and you can adjust the sprite resolution through the "_options.txt" file however you like.
Regarding the object hierarchy — implementing it is just as painful as it is to use right now, but I’m trying my best)))
Thanks for following the game!
