StudyArcade now records "normal" and "reverse" study progress independently. Which is to say: your ability to remember that "il gatto" means "cat" is entirely separate from your ability to remember that "cat" means "il gatto". This is more similar to how Anki and other flashcard applications work.

All games can now be played using "Normal" "Bidirectional" and "Reverse" modes (not just Flashcards).
