FlashBoss is stable

On the bugs themselves:

The early build had issues that went beyond rough edges. Some users have experienced more serious hiccups, including display and save state issues. These have been completely addressed in the latest release. If you have experienced issues, my apologies. Please start new with a fresh profile.

What's fixed:

Steam Cloud saving. The major technical hurdle and the source of most early frustration: master selection bugs, profile-switching issues, unstable save state. All completely fixed.

Full audio caching is now built in. Generates pack audio up front for instant playback during sessions. See the Help menu, Option 8 from profile selection.

Boss fight audio. Hear the drums of war as you face off.

Formatting issues across the interface. All addressed.

One known issue remaining:

On macOS, the terminal window doesn't take focus when FlashBoss launches. You have to click Terminal in the dock to bring it forward. A fix is in development and will ship with the final language packs.

On the release schedule:

Italian Pareto 2 and Latin Roots will land after the Mother's Day weekend, a few days behind schedule. This closes the content release season for FlashBoss.

Coming to the website over the next month:

Full word lists for every pack are being published on dedicated language pages — browse the entire vocabulary curriculum freely, organized by cluster, with English translations.

Bug hunting season is open.

The system is ready for serious play. If you tried FlashBoss earlier and set it aside because something wasn't working, now is a good time for a second try.

If you find anything broken — no matter how small — I want to know. Reply here, make an error report at the website, or email. Newly reported errors will be compensated with a dlc pack of your choice within a week of confirmation. Factual errors in the card and lesson content can also receive rewards.

flashbosscontact@gmail.com. Every bug reported from this point forward will be addressed in the next patch cycle.

And on a personal note, FlashBoss was released in good faith, in the belief that it was working correctly. As a solo developer, I was unaware of the difficulties I would encounter in the release process. A big advantage of Steam is that updates and improvements continue to ship free. FlashBoss will continue to improve in quality over time. Thank you for your patience.
