Thanks for your feedback! Sorry to hear there were issues with spacing - feel free to contact me if there are any specific fixes you want me to make and I can post an update. :)
A = Original Spacing
B = Updated Spacing (1 pixel space before and after each character)
I only edited the lower case letters (in Unity, using TextMeshPro's font asset settings) but I found a lot of them would have uneven spacing leading. It's very apparent around much of the punctuation and thin letters such as "i" or "l".
If you were able to update the font directly, that would be wonderful : ) 💜
