I loved LOI and hated COD. All advances made in LOI (like axing leveling up, not having an abundance of items, simple gameplay, a nice hub structure) were all reversed in COD, along with a useless Innocent Devils feature, the same damn combos for every weapon, and larger, more boring, rooms.
LOI is worlds better, being one of my favorite games of all time (Nanobreaker also is a sweet game with the same engine, BTW), and COD is brutal. Quite possibly my least favorite Castlevania.
