Currently this is what the maps around the ship look like. It doesnt give enough directions for anyone starting out especially when the only helpful thing (in my opinion atleast) is the each deck thing (the one thats below the top-down view). The top-down view in particular still doesnt make sense to me after staring at it for a good couple of minutes.
My suggestion is this:
Take a couple of notes from these pictures.
These are what real ships maps (actually deck plans but still) look like. They're easy to understand from first view and don't require that much decoding.
I think there should be a touchscreen map that you can scroll through every decks view with and it shows where everything is just like the examples i gave. If a touchscreen map would be too hard or "impossible" you can always do it on the current screen but smaller. (or like some real ships on the wall next to the stairs / elevator)
Also for the map below the top-down view thingy:
It shouldnt be just boxes floating, it should be (like the example) modeled after the ship.
