What about offering the glyphs as individual svgs as well as the font, that way people that need to optimise can. It would also be easier to recolor svgs and potientially do some fun animations on websites :) You could offer the font for free and charge for the svg pack; I would totally pay for it :) kinda in love with the pixel heart and would love to use it on my website when i go live. Kinda like what they do on https://game-icons.net/
