How many players must own Mario Bros for 2 player mode

mario-brosnintendo-3ds-3dsxl-2ds

There's a version of the original Mario Bros (https://www.nintendo.com/games/detail/steaDexI7H4v0UEWC20wW3alYYaGW5bz) available for the 3DS on the Nintendo eShop. If I buy this eShop version, can I play with my friends even if they haven't also bought it?

The page states "2 Player Alternating", which usually means that you will have to do something like pass the actual 3DS from one player to another, rather than, say, playing together through an online connection or other means. So technically, yes, it appears you can play with friends, but it means that they likely need to be in the same physical space as you so you can share the console.
