Hello everyone! Unknot!'s first major update, v1.1.0, is now available. This update introduces Research Level, improves Stable physics, and adds a new Steam achievement.
Research Level
Add: 10 optional Research Levels, available from the title screen.
These puzzles are designed to support research into knot puzzles and open problems related to unknotting in mathematical knot theory.
Research participation and data
Before playing, you can choose Agree & Upload or Play Only.
Play Only lets you play every Research Level without uploading research data.
If you choose Agree & Upload, de-identified puzzle-solving data may be uploaded after you clear a Research Level. This may include the level number, clear time, swap count, input events, rope states, and an anonymous Research Code.
This data does not include your name, Steam name, Steam ID, email address, or any chat or personal message.
New Steam achievement: important unlock condition
The new achievement unlocks only after you first choose Agree & Upload and then successfully clear any Research Level.
Agreeing to upload without clearing a level does not unlock the achievement.
The achievement is awarded when the level is cleared. The upload itself does not need to finish successfully.
Choosing Play Only still gives access to every Research Level, but does not unlock this achievement.
Stable physics
Improve: More stable rope release, collision, and closed-link behavior in Stable mode.
Fix: Saved physics settings and rope state now apply correctly when entering a level or loading a save.
Please note: Research Level always uses Stable. Stable uses more precise calculations, but the controls will feel different from Default.
Other improvements and fixes
Fix: Research Level icons now display correctly in exported builds.
Fix: Some Research Level buttons could open the wrong level or fail to respond.
Improve: Upload progress, success, and failure are now communicated through the clear screen. If an upload fails, the data remains saved on your device.
Thanks for playing and for helping us explore knots!
