This world was generated from a real textbook. ← → to move, Space to jump, ↓ + Space to drop through. Use the on-screen controls to run and jump.
How it works
Three steps from a file to a world you can walk around in.
Upload your material
A textbook chapter, lecture notes, a paper. Any PDF or EPUB, in any language.
A world is generated
AI writes the maps, the characters and hundreds of quiz questions, all from your file. Takes a few minutes.
Play, and learn on the way
Every character is a quiz on your material. Win and the world opens up. Miss and you will see that question again.
Two games, one textbook
Prefer exploring to jumping? Every world is also an overworld: walk the maps, read the signs, open the chests and challenge the characters. Each battle is a quiz, and a boss guards every map. The demo above and this one share the same world.

Built for retention, not for cramming
The mechanics are the study method. Active recall and repetition, disguised as a game.
Missed questions come back
Every question you get wrong is re-asked in rematches and boss fights until you get it right.
A boss guards every map
Beat enough characters to unlock the boss, then beat the boss to move on. Progress you can feel.
Streaks pay out
Consecutive correct answers multiply your XP and drop items. Stay sharp and the rewards stack up.
Your language, not ours
Questions are written in the language of the document, whatever it is.
