Latin Core is out: FlashBoss meets its first dead language
Latin, the first dead language Latin Core is live: the first thousand words of Latin, in the FlashBoss way — 20-word clusters, spaced repetition, a boss at the end of every cluster. We rehearsed the method on two constructed languages, Esperanto and Toki Pona, and learned how far it stretches. Latin is the first language with no living speakers to check us, and the answer is the same. Built to…

Hear every FlashBoss voice before you buy
Every voice FlashBoss ships now has a sample on the website. One page, one real sentence from a real card per voice, read by the exact model and speed the game uses. Nothing recorded specially, nothing sweetened — if it sounds wrong there, it sounds wrong in the game. The two voice DLCs sit beside the voice they replace, saying the same sentence, so you can hear exactly what changes before you…
