Yes, it’s not ideal for coop. It still still miles better than Mario Bros U Deluxe which - together with issues listed in this post - had player collision. This made the game more frustrating than anything as suddenly there were more obstacles for everyone in a shape of diffetent players.
It is a problem with 2D mario. It’s the same there was on Nintendo 3ds - the camera is your enemy in coop. I think 3D World is much better suited for shared screen/online as there’s simply more space for the players.
It is a cross-platform terminal that supports only bash and only on Linux and MacOS
