Questions in Floating Sandbox

hello, can you put your own music and sound effects in the game? I tried doing so but it showed an error

Hey uhh big ships such as carnival glory kind of lag or something while I have 60 fps, does this happen to everyone or is it just me? It makes them kinda unusable...

will there ever be floatation devices? like say if you wanted to raise a wreck.

to get this game you will search in what is in your mind then install it

Is there a way i can screen record floating sandbox? OBS will not work.
