We've seen that there are hidden goodies all over Castlevania, but there's one that's so secret that it's not even in the manual and a lot of people don't even know it exists: a 1up
To spot this rare gem, first make your way to the fifth area, which the game calls "Stage 13". After you leave the first screen and destroy a couple of skeletons, you'll come to this formation.
Most people will walk down the stairs and continue on, but if you just walk to the right and press against the wall for a few seconds
A 1up will appear!
You only have a few seconds to grab it, too, so make it quick!
