There were times in this game i genuinely got creeped out because this game is unapologetically evil and at the time ive never played a game like that.
The gameplay is what kept me coming back to it because this game plays like Zelda in the sense that it is an action adventure game.
i would say this game is like a mix of Diablo and Zelda, it has similar puzzles and it even has animal transformation powers you get in altars
I think you can turn into a wolf and a bat along with other animals and ofc these transformations are needed to pass certain puzzles in the game which are actually not very hard to figure out.
Overall this game was great and it's one of my favorites action adventure games of the ps1 along with Brave Fencer Musashi.
