heey, that's an amazing font you made :D congratulations!
but I am having a problem, I'm trying to use as 8px font, but it only works on 16px

Hi, thank you!
That's not my font in your screenshot... But you're right. Also, the text seems to be drawn 6px below what's expected...I'm gonna take a look on this issue soon for an update, It may take a few weeks.. For now, you can set it at 16px in Godot, your text will still displays cleanly at 8px tall.
