My immediate thought was:
"This is either a very very old language or a very very modern one."
My reasoning: This language isn't optimised to be written with a quill or brush. It's a language which, while writing it, you will have to keep stopping to take your drawing implement off the page/tablet. The letterforms are quite precise, with a lot of meeting rather than crossing lines, so you'd need to write it fairly slowly and precisely. I'd therefore assume it's designed to be written with a stylus held in an upright sort of position, perhaps on a clay tablet (the dots suggest poking a pointed stick into a tablet), or to be printed by machine rather than written by a person. An alien species that writes by scratching a surface with a claw is also possible. It definitely isn't designed for writing on stone with a chisel like roman letters or norse runes, too many tight curves and even little curls.
I'd also assume that if there's a spoken equivalent to this language, it would be measured, precise and very rhythmic, with phrases that carry a lot of meaning, because the written version isn't well-suited to stream-of-consciousness waffling.
