The Bloodborne PSX demake is now available for download for free, and it seems like it is a very faithful recreation of a chunk of the original.

The demake, which has been developed by Lilith Walther in only 13 months, features the first 2 bosses of the full game, the Cleric Beast and Father Gascoigne, multiple locations, and a few extras. Judging from the comparison video put together by ElAnalistaDeBits, is an extremely faithful demake, despite the obvious visual differences.
