I'm biased; it's my favorite NES Castlevania game
This game is amazing! Not only the levels were incredibly cool, but you had the choice of which path you would take to get to Dracula's castle. On the way, there were 3 fights that at the end would give you the choice to be joined by an ally. You could switch on the go through a level, altering the level itself, and changing the player movements and attacks drastically. This game brought to the Castlevania canon Alucard, who would be the main character of Symphony of the Night. The BGM is one of the most memorable form the 8-bit era. I still have a few of those songs in my mind from time to time, and I've played a TON of games in my life.
And the game is HARD! I only beat it once, and that was because I got very lucky. It has great replay value, as you can try to beat the game through different paths and with different allies. There is a different ending with each ally you finish it with, or you can also finish it solo.
Hands down a great game to have in your Virtual Console collection, if you like platformers. Oh, and by the way, the movie I guessed correctly was Shoot to Kill, with Tom Berenger and Sidney Poitier. I still remember that.
