Hey thanks for your feedback.
Leone is the name I have choosen to give players my best score ;-). Ninfar seemed to have reached 10 second... If you want to improve, I think you should carefully study the mechanic around the blue filler, especially what happens when you click too much on it!
For the bar filling, I used TextureProgress Node in Godot, you can find a tutorial on how to use it here:
you can check the source code (project) if you want to understand more in detail.
