Bichométrico Fifteen Sliding Puzzle

Game that I am developing for Bichometrico (link: https://bichometrico.com); The main code was a Coder-Dojo script (link: https://github.com/programaths/coder-dojo-godot); I added some modifications to sync between screens; some additional effects I'm adding too; I kept the movement of the pieces using Tween Node like original code, which I think it was a brilliant solution.

The soundtrack is: AzzyGames https://devdevious.itch.io (https://www.patreon.com/sharkybutt)
