When using Paper2D, how do I prevent my textures from getting blurry after exporting my game?

My characters are pixelart characters, I am designing a 2.5D game, I use Paper2D. Whenever I export my game my characters become blurry but the rest of the world is clear. Moreover, when I start my game from within the game engine, everything looks clear.
Help MEEEE ;(

This is from the executable of my game and motion blur is off, but every Paper2D looks like this blurry:

When I run the game in editor, it looks perfect:
