Is my progress saved?

Yes — your level progress, in-progress drawings, and streak are saved automatically on your device. Nothing is sent to a server, and nothing is shared between devices.

How do I reset a level?

Open the level and tap Reset below the canvas — this clears your current drawing so you can start over from scratch.

What's the difference between DFA and NFA mode?

DFA requires exactly one transition per symbol from every state. NFA allows multiple transitions on the same symbol (or none), plus free ε-moves. The in-app "Learn the Basics" walkthrough covers this with interactive examples if you want a refresher.
