The third level definitely gives a sense of almost got it but so far away. I felt like I had the right ideas, but they never panned out. Part of the issue was how long it takes for it to play out. Forget to put something down? Well got to reset and do it again. Maybe saving the last configuration, then letting the player move objects around could help ease that. I see you used Godot 4.3, the music restarting constantly was a bit annoying. Might I suggest making a MusicPlayer node and running it in the Autoload so the music can run independently from the scenes themselves.
