I played on my phone on the itch app and can't seem to find a way to close the score menu (exit button don't work?). For my improvement suggestion I'll mention bone2d node on godot, for the type of shooting that you are going for you could use that to have the arm of the player rotate 360 degree as oppose to the 8 direction if you would like. Good job on the submission & goodluck on your godot journey!
