This version of SOTN is kinda "weird". It's not quite the Sega Saturn version yet it has some extra stuff from that port. There's a few extra familiars and Maria can be used as a playable character after you beat it once. Other than that it's just SOTN "classic" with a few additional bells and whistles!
PS: Rondo Remake is HARD! I'm already shouting obscenities at it. lol. For the record the remake is mostly the same but it's now 2.5D graphics and the characters have been re-designed a tad.
