I don't know why this game has no comments at all, it's one of the best games in the Novice section that are not Interactive Novelles or Platformers.
I could never imagine a way to implement a rhythm game with polarity but here we are. I really liked the transition from the controls to the main game (one of the best I have seen someone do in Godot).
I have never attempted to create a rhythm game but I believe it is very hard to sync the beat with the upcoming dots, you did a good work synchronising them. If I had to add something I would add some particles when the electrons align with the circle (or an animation where they attract to one of the poles of the magnet).
Overall, this is a solid entry. Didn't encounter any bugs and had a good time remembering the days when I still played OSU. Wish you all the best in the voting period my fellow Godot programmer (and maybe a strong opponent for the top 3).
