This menu has two functions: one is the menu and another put the game on pause. This menu will open a new screen, with a background that represents the deep sea, with dark blue and green colors making waves and some blurred creatures (maybe the Butterfly Conger) in the back moving randomly. It will sound the main soundtrack in the background and with the effect of being underwater. I think it can be funny if the player pass to much time in this menu (maybe 5 or 10 minutes) that they will start to listen to the voice of the Conger and maybe this one can appear on the screen like a jump scare, with his shining eyes looking for the player.
This menu will have the basics options (Save, Save and Exit, Load, Main Menu, and Options) and the Tutorial.
This menu will have sounds when the player passes by the different tabs. I thinking in a metal sound (like a bell or something like that).
