Music and minor bugs fixed

Hello again, today I bring a new version that adds minor fixes:

-The health bar now updates properly, not the numbers, rater the values of the bar itself, making weird animations when player gets hurt.

-Added music to the game, one for main menu and another in game.

-Added sound effects when tap on any button of main menu and pause menu in game.

-The boss “a hand” now triggers its attack animation and voice line when defeated.

-Credits scroll is now slower.

Pretty sadly I will stop upgrading this game temporarily because my lack of programming skill.

I will start new projects on godot4.3(beta) so I can get used to changes, and learn things like tree behaviour or attach upgrades like the wands in Noita.

Hope you enjoyed this little game and if you find anything to changes, feel free to comment and will do my best to fix it.
