How do I make my tiles from appearing "separate"

It just doesn't seem to go together. I am using the snap grid which is 32x32. My tiles are 64x64/128x128 but they don't seem to be blending together. I also cropped transparent edges too. So it shouldn't be an issue?

Please help. D:

I am sure many here would gladly help you, but not much I can get from your description. What exactly do you mean with "blending together"?

I want to remove the white lines and gaps. So it would be perfectly black.

If you attach the cap.x, I will fix it in 1 minute and leave you an explanation in a comment!

Or if you don't want to post the cap.x, use tiled background and make sure you don't have white edges in your sprites.
