So I finished Castlevania last night: got the good ending with Reinhardt, no extra bosses before Dracula. I was surprised at how streamlined the back half of the game felt after the Castle Center area: the levels got smaller, more linear, and the bosses easier! Death, in particular, was a pushover, especially compared to his fights in other Castlevania games.
The Tower of Execution was probably my least favourite level over all, just because the framerate was atrocious. Normally I'm not a stickler for a rock solid framerate, but it seriously dropped to about 5 fps for half the level!
All in all, I really enjoyed the game! I unlocked Hard mode, which I wish was an option from the beginning, since I found the game to be pretty easy for the most part: I never spent a single dollar in the store to buy items! I also had so much roast left by the final form of Dracula that I didn't have to learn his patterns, I just whipped the shit out of him and ate chicken and beef until he died, haha.
I played a few minutes are Carrie, but I think I'm going to take a break from the game for a while. I'll probably eventually just play Carrie in LoD, when I get around to it. I am glad I played the original before LoD though, as it'll just make that playthrough all the more entertaining, as I hear it fixed a lot of the problems of CV64.
