They had good intentions with this game but it´s broken on so many levels. Calling this a f2p game is a shame. Unlocking major parts of the game for money only as well as better subs makes it just a demo and pay2win. I like the immersion of a sub in full 3d under water but whats the point of the periscope? you can´t even stay under water to see above the surface. Morse chat is a nice addition but only nintendo could add it as the only way to communicate. You have a mic and a cam in every defice. Just use it. Graphics are aweful. It´s confusing to see a first party nintendo title with such a lack of polish.
you can play against similarly ranked opponents as opposed to random ones so the "pay-to-win" aspect can be avoided
