im making a game very similar to "Zelda: A Link to the Past" for SNES and i was wondering if i rely mainly on BitBlt for doing all the animation would I be able to accomplish making a game such as Zelda? So far I have the majority of my game engine made, the main character walks around and there are soldiers which attack you and hit you, you can walk to the edge of the map and it continues on like Zelda, etc. But for some reason I have a feeling that BitBlt won't work to well once I start doing more complex animation and more enemies on the screen and it might just slow down to much, will this happen? Imagine if Zelda was created using BitBlt, would it not have been as smooth or would it be just the same?

I know this is a stupid question but I just don't want to work on this game for a month and find out all that work is pointless because it won't turn out good. Anyways is BitBlt powerfull enough to make games like Zelda is my final question? Thanks for any replies.
