Fun fact KGWZ released one of their albums completly free (i guess public domain) and encourage you to play with it as much as you want :)

There is a way to play it. And it works very well.

Switch emulator

You might see where I’m going with this. Now, I don’t know if there are any for iPads, but you can download some for Android. Personally I use SuYu.

Switch rom

You will need a .nsp file of the game + .nsp file of any updates you want to include. You can get this file from your nintendo switch (or you know, the high seas) and then import it to the emulator. For me, it runs at about 15 fps on a 4 year old Samsung phone (no Snapdragon), which is playable.

The game registers screen taps very well and you won’t have any problem with playing it.
