The game's interesting, and its setting made me question what was going on with the characters and the place, well done! 😃
From what I've read, this was your first time developing a 3D game with Godot, and you did it really well, keep working and improving guys, this is a nice first step into the engine! 😁
I'd recommend making the boxes movable in any direction once you grab them, it's a little tedious to change directions each time you need to move one. It's just a detail, but it will really add to the final product, trust me 😊.
Good job! 😃
