A dungeon-themed platformer on the original PlayStation. I think you could choose between first person and third person view. In the final confrontation, the boss runs at you, but attacking him directly causes no damage. You have to throw stars (or some projectile spell) at a few towers to kill him. Anti-climactic. Control was clunky, graphics were not great, and the game was a piece of crap. But I played it with a dear departed family member and want to play it again for sentimental reasons. I have scoured image search and someone's list of 240 dungeon-y games on the PS1, to no avail. It is obscure for good reason, but I would love to find it.
EDIT: Found it, thanks to this video compiling all PS1 games released in USA: https://www.youtube.com/watch?v=B69v7vV2m74
Good ol' double speed and fast forward keys to the rescue for such a long video.
Crusaders of Might and Magic! A piece of junk which should be played by no one, which I am now happy to play.
