Especially considering this is a first time Godot project, this is really solid! When you hit the bounce just right and get schmooving it feels awesome. I would say the arm needs a little tuning, it can be pretty unforgiving--it might just be me but it doesnt always feel like it is visually lining up properly with the angle it winds up sending you, and the arm rotating with the ball itself makes it sort of impossible to control if the ball is rolling in the same direction the arm is spinning. That said it's got a lot of charm, I'm very fond of the colored pencil levels and the blobby character.
