About FlashBoss

FlashBoss - about the game
FlashBoss Steam Store Description

FlashBoss is a terminal-based vocabulary learning game that combines spaced repetition with RPG mechanics. Create a hero, choose a master to guide your journey, and battle through vocabulary clusters to achieve language mastery.

The Core Loop

Each day, you'll review flashcards using a proven spaced repetition system. Cards you know well appear less often; cards you struggle with come back sooner. Maintain your daily streak to build momentum, or use the Grimoire to bank extra days of practice as "Drive" — insurance against life getting in the way.

Boss Fights

Vocabulary is organized into thematic clusters, each guarded by a boss. Defeat the boss to unlock new words and advance through tiers. One step forward, two steps back: An incorrect answer pushes you toward the edge, a correct answer drives you forward!

Choose Your Master

Six masters offer different philosophies and session limits:

  • Luna — Gentle and encouraging, limits daily Grimoire sessions to prevent burnout

  • Claude — Analytical and precise, unlimited sessions for the self-directed

  • Odiin — Stoic warrior-poet, unlimited sessions for the dedicated

  • Shen — Wise and measured, moderate session limits

  • Kitsune — Playful trickster, unlimited sessions with a mischievous edge

  • Aquila — Noble and disciplined, moderate session limits

What's Included

The base game includes German Core and Esperanto Core — 1000 words each with full example sentences and native audio pronunciation. FlashBoss is designed to get you from zero to interacting in the target language. Additional vocabulary packs are available as DLC.

Why Terminal?

FlashBoss runs in a terminal for that retro aesthetic and lightweight footprint. Language education shouldn't require expensive equipment.
