I've done some more work on alphabet I created for Spryke. Firstly, I gave it a name (Sprykski). Secondly, I've assigned phonemes to it.
In other words, Sprykski is now fully capable of being used to write English, Polish, and many other languages :)
It also contains a number of more unusual sounds (including several clicking sounds found in African languages), which should lend itself well to the exotic inhabitants of Spryke's universe!
