This is a cool font, but the size of the glyphs at each point size is bigger than the bounding box, which seems to cause problems in some apps (Unity for me). I managed to fix it by copying the glyphs over to a new font file with bigger bounding boxes. I did it by hand so it might not be 100% pixel perfect with the original but if other people are having problems with the size, I put the resized versions up here:

The size of the 6pt (8px) version in the original is equivalent to 12pt (16px) in the resized version, so 16px will look best.
