As discussed in this Twitter thread, this game is not from 1987, but is in fact a very recent creation by a game developer claiming to have "remastered" this title, as part of a marketing campaign:

I love it
I'm desperately trying to find a copy of it
I remember it was a very good game of the same genre of another world and flashback, at first I thought it was a sequel but I don't know, I think it was made before, so I don't know what to think, it's a shame that is so difficult to find on the web
I really hope that it's possible to play it again

I don't know what happened to this game, or why everyone stopped talking about it, but something so ahead of its time should be remembered st least as much as other classics such as Prince of Persia or Another World.
