1. How often does day change to night and vice-versa? Specifically, what is the ratio of playtime to Castlevania time. For example, 3 minutes of playtime in Simon's Quest = 12 Hours Castlevania Time --so day/night switch every 3 minutes.
Don't know.
2. Do the game environments depict daylight when appropriate --like Simon's Quest? And if so does the music change from day/night?
Yes.
3. Can you give examples of daytime/nighttime events involving characters, puzzles, or time sensitive equipment? BTW I do know about the Moon/Sun doors and the time sensitive ending.
4. I know that Dracula's monsters are stronger and more plentiful during the night than during the day (again like Simon's Quest) --but I'd also like to know if there are any exceptions. Also do monster behaviors change --like clinging to shadows to avoid daylight?
Vampire enemies are only active after sunset or in places in the castle itself where there is never any sunlight.
5. Are there certain monsters found only during the day/night?
Vampires
6. Are the indoor environments affected by the daylight hours at all? Or such places their safe haven for Dracula's monsters like the Mansions in Simon's Quest?
