zooming in camera in ex-2D

Hi. I know that this is probably the wrong place to ask this, since it's actually a question about the 2D-plugin "ex2D", but since they have no forum of their own, i'm asking here.

I want to zoom my camera in 2x, so that all sprites are magnified two times. I have put my camera with ex2d components to pixel-perfect. When I mess with the custom resolution setting of the camera, the sprites do indeed become larger / smaller, but they also become fuzzy. I don't want that. Basically, i'm going for the oldschool looking sprites with large pixels. How do I achieve this in ex2D? (I am also willing to try 2d-toolkit)

Thanks in advance!
