I feel like having to pay for Nintendo Switch Online to exclusively play Secret neighbor is a little bit absurd, many games, such as Fortnite, Ninjala, Warframe, Warface, Pokémon Unite, Yu-gi-oh Master Duel, etc.. are not only "Free" to download (Unlike Secret neighbor, which requires you to buy it first), but they're also free to play without Nintendo Switch online services.
Free games usually have in game purchases, but having to buy a game then having in games purchases on top of that is not good at all, I personally have no problem with it, as I occasionally drop couple bucks on Secret neighbor to support the Devs, but having to pay for Nintendo Switch online just to play it exclusively is going to put me off the game, even though I like it a lot. (I don't personally play other AAA games online, and the other games I play don't require NSO).
I'm not speaking for myself, as I'm sure there are tons of people, who are mostly kids, are unable to constantly afford Nintendo Switch Online and are often left to play other games and probably forgetting about Secret Neighbor in the process. The game not being available on Android as well is not helping justifiying its case.
I'd love to kindly ask you to remove the requirement of "Nintendo Switch Online" to play the game, just like every other major game availalbe on Nintendo Switch, not only it'll increase the number of players but also the popularity of the game. Again, I'm not asking to make the game Free, I understand, I encourage people to buy it and support the devs, but at least make it free to play Online without it being bound to a service and not being available for free on Android devices.
