Not only are people trying to make a Remake of Soul Reaver there are also people trying to make it in 2D.
The game is pretty small and there are only 3 types of enemies Slaugh, Dumahnim and Melchiah which is a boss. It pretty much ends after the Melchiah fight, there is a glyph shrine that is unfinished but i think it was supposed to give the Fire Glyph.
Kain's citadel also leads to the glyph shrine.
