Combos, Fever & Shields
Mistake-free writing builds a score multiplier up to ×3, charges Ink Rush fever for double-point bursts, and banks shields that save your run. Accuracy—not speed-spam—is always the winning strategy.
Boss Battles & Revenge
Tough characters appear as boss bricks—defeat them with a perfect clear for bonus points. Miss a character? It comes back marked for a revenge round, so your mistakes become your next victory.
Ghost Races & Run Ranks
Race the ghost of your best run on every lesson and watch the live +/− delta. Each run ends with an S-to-D report card naming your trickiest characters—your next session writes itself.
Brick Wall Gameplay
Clear character bricks by solving quizzes from rotating bottom characters. Chain multi-brick clears for bonus points while the heat ramps up as the wall closes in—pressure you can see coming.
Progressive Unlocking
