Castlevania for the NES. I mean really this game has hearts in it but the hearts don't heal you, the only thing that heals you is a porkchop which their is only one of these in the 1st level. Why does simon jump backwards when he gets hit by any of the enemies? Than their are hunchbacks that jump all over the place. Than you have medusa heads and bats that fly across the screen which I don't think you can duck or jump over these enemies, so you can only attack them. And 1 level has medusa heads coming at you from the right direction and the left direction. Why do both enemies have to attack you from both the left and the right? And why do the knights take 9 hits to kill? And to kill Dracula you need to have as many hearts as you can get or he is going to be not easy to kill. And than they give you an invincibility potion that lasts for maybe only 3 seconds. You have to duck under enemy fireballs. And their are no passwords in this game. No way to save the game. And if you fall into a pit you instantly die. And when you fight Dracula you have to jump over 3 moving fireballs. You can't move while jumping. Some of the enemies will get rid of half your life if they hit you. Take a look at the way each level is laid out ? perfectly so, as if to ensure that every single touch of your controller is perfectly timed. The whip has a delay. This is a game that takes TIMING and SKILL that is LEARNED through trial and error. That is what made the game so great. Every level and boss has a pattern. This is a frustrating game.
