Pixel Sprites Blurry?

Hey, sorry if this is a totally nooby question, but when I upload images to a sprite in their normal pixel sizes(I'm creating a pixelated game) when I play the game I'm zoomed out really far from the sprite/background, and the pixels are really blurry. Is there a fix for this besides having to go through all of my sprites and resizing them?

You can look in the project's properties, especially the linear/point sampling and the downrate quality.

Importing sprite at the correct display size is also a good way to go.
