Oh, i get it. The lines between the grey platform are cuz your object does not line up correctly, most of the time. The player one, i have no idea. Ask around it with some screenshots.
The thing is that as far as unity is concerned they were each 1 unit apart at 8 pixels per unit and all my sprites were 8x8, they should all be perfectly lined up but the slicing seems off and I can't pin down the issue.
