I don't really know but quick enough, maybe 1 or 2h. Fonts are things i can make more quickly, i think it's an ability i kept from demoscene.
How long did that font take you to do? It's beautiful and it makes me sad I never see pixel artists for hire who show fonts in their portfolios.
That's fast. That gives me some hope I might one day find some font artists! Either way, awesome job.
