hmm… I don’t really know anything about JoiPlay.  But there’s an android build in SmilingDog’s discord server. Maybe try that?

and you opened game.exe, not index.html, right?

you don’t need to install it into the main game. It’s a standalone executable. Are you sure you downloaded the right thing? You can get the correct download from here. https://ncplus.xyz/download.html

What happens when you try to run it?
