Try Tone Threshold
One question. One doorway. No rush to answer.
This small web version gives you the free core of Tone Threshold: stand before one question, cross when ready, and keep a private mark when something has not finished with you.
Map
The web version is a simple doorway.
It keeps the free Threshold experience intentionally small: choose a doorway, receive a question, cross to the next, and keep only what still has weight.
Stand
Let one question have the whole room.
Cross
Move only when the answer starts falling silent.
Keep
Save a mark privately in this browser.
Language
Doorway
Choose where to stand.
Self doorway
Who is choosing before the chooser explains itself?
Stand where the answer falls silent.
No completing. No optimizing. Only the next doorway.
