I am not sure what you mean by the edge of the tiles. But I think this is the font's visual, as this is just a text with an outline component.

Ooh right. I couldn’t find what was causing it when I was working on the game. And now I tried to do your suggestion. But I can’t find Anti-aliasing settings. I think it should be in Edit->Project Settings->Quality. But Anti-aliasing just doesn’t appear there
