Enemies in Castlevania are generally not dangerous. In the very early Castlevania games there were those skeletons throwing bones at you near pitfalls, but a lot of 8-bit and to some extent 16-bit games were designed to be very arcade-like and unforgiving. No continues or saves, etc.
am talking about 3d games that are slow. castlevania games are very slow paced similar to dark souls.
and by dangerous I meant they can potentially do a lot of damage. I mean in dark souls you kill the goons in two hits or something like that. as long as you are careful that is. but if you get careless you can easily get staggered and chain damaged by them
in castlevania a goon can easily hit you while jumping and ruin your day.
