hm_pd_003.iso
From The Lost Media Wiki
It looks like a few people were looking for a build of the game called "hm_pd_003.iso" which was supposedly version 0.03. The torrent of it has been dead for a while but I found it on Usenet (https://nzbking.com/details:4f8a1ea64f9bb665865251a7/)
A mirror of it can be found here: https://mega.nz/file/bMZQEBzB#FRd6tjbt5Pn89hFOHgNGFpshbKJAQWmeeSs1mKdULyk
It's the 2nd iso that the person in the projectdiva.net thread was talking about.
