thanks for the feedback. about the braces please see another comment below. the issue of needlessly complicated braces has been raised quite a few times now. a variant could be considered if there is more interest.

this particular font is quite simple and doesn't contain any ligatures, etc. so most of the design is in Fontforge. i didn't start from scratch. it started out as a customised version of Source Code Pro (released as Hera and currently archived in my profile) but i borrowed many glyphs from other fonts and modified many others to the point it became a different font. you can open the .sfd file directly in Fontforge to edit and modify it yourself.
