Another Godot User i see.
(You definitely had enough time to put music, you just didn't lol, i know that because myself i only used less than 24 to develop this game, counting some small progress made in the first days and the hours spend at the last moment trying to put something together xD)
Anyways seems a cool vibe.
PD: I thought you had done like me and leaved it without even a simple game loop, but i then turned back and saw the press "F" thing haha.
Very cool.
