I have started this game with a little knowledge of German I started by doing the BossFight which i found a good challenge. I also do the daily lessons and have found this good with good example sentences. A good way to learn new words and to see them used in sentences. i would recommend this to start learning a new language.

works well on linux, the UI is def a unique and welcome simplification on the old DOS console RPG menus, I quite like it and will def use this over ANKI just due to the pre prepped "cards". 100% a learning tool i would recomend.

This game has been really well thought out. After about 9 hours I’m still remembering the words from earlier levels, which shows how well the mechanics stick with you.

It’s simple to start but gets properly challenging, and it has that classic “one more try” loop that keeps pulling you back in. The boss fights are a lot of fun too and break things up nicely. Really fun little game.

Latin Roots is Live — the Release Run Ends Next Week

5 days ago
Latin Roots — Out NowLarge vocabularies are not built one word at a time.They build from the root buried inside a word and the prefix bolted to the front. Latin Roots hands you that machinery. Learn a single root — par, to make ready or make equal — and a dozen words open at once: prepare, repair, compare, parity, disparage, even emperor and rampart. — 500 cards, 1,000 words, across five tiers that climb from transport to perfidious and stringent. Every card shows the root, its Latin source, and exactly how the parts assemble, with synonyms and antonyms to place each word precisely, and clean Piper audio on every word and example.The complete word list, every reference lesson, and a playable boss-fight demo are free on the website for Latin Roots and all material in the FlashBoss catalogue — browse the curriculum before you buy. Latin Roots is the classical and scientific layer of the Roots Series, sitting alongside German Roots and Norman Roots.Boss fight demo The word list The lessons The website updatesThe whole site has been rebuilt, or is undergoing renovation. The headline addition is the Word Lists page: free, printable vocabulary lists for every FlashBoss language — English, Italian, German, Spanish, and Esperanto — the most useful words in each, frequency-ranked and grouped into thematic clusters across five tiers, each paired with its English translation.Closing the season — Italian Pareto 2, June 11Italian Pareto 2 is in final editing and goes on sale June 11. That's the last drop — it closes out the release run that's been shipping since Easter. By then FlashBoss will have its full planned catalogue across five languages.One outstanding bugThe Grimoire is awarding double Drive in German (at least — possibly elsewhere). A fix is coming shortly. In the meantime: bank the streak protection while it lasts.Steam Summer Sale: June 25 – July 9 — all FlashBoss content 20% off for the full two weeks, with a free text-to-speech generation window arriving in time f...
