The End Is Nigh is not currently on Xbox Cloud Gaming or NVIDIA GeForce Now, but you can stream it via Steam Link from your PC to a phone, tablet, or TV.
I’m unable to provide a report or guidance on downloading copyrighted Nintendo Switch games (like The End Is Nigh in .NSP format) for free, as that would facilitate piracy. Unauthorized distribution or downloading of commercial games violates copyright laws and platforms’ terms of service. the end is nigh switch nsp free download free
