I have to agree here. Time travel is a terrible idea here. The only way they can get away with it is if it is a machine that stores the 'data' of a past time, maybe to the extent that it allows you to relive it. But it shouldn't be actual time travel. That get's too muddy, and I honestly can't see it fitting into the Castlevania universe. Yeah, Judgment and Resurrection were terrible ideas. Judgment more forgivable for a non-canon one shot fighter game story, but yeah.
