In my opinion, LOVE's default font (Vera) isn't a very clean font. It has some kerning issues and it just doesn't look all that nice.
I've taken a few screenshots of various fonts that may be suitable replacements. The following images have their fonts rendered at sizes 12, 14, 16, 24, and 28.
My personal vote would be Noto Sans Regular as it both looks nice and is Google's currently maintained font.
