That version was 1.41 of the demo unless that is specifically what you are looking for. The latest and complete version is still 1.0 as far as I can tell. You can find links in [RELEASE] AM2R - Another Metroid 2 Remake 1.0.
@FAST6191 - totally agree. not sure the reasons people use vanced/revanced over newpipe.
I guess it's because of people still wanting to use their yt account (with vanced)?
