# Level System

Configure the title-side level/scene manager and the gameplay level goals together. Existing gameplay controls determine fixed/random score targets and rating thresholds. Do not interpret this as stars being awarded arbitrarily: inspect the actual displayed values and test the configured goals.

The next-level action depends on the level system and an available next destination. Match exact destination scene names against enabled build scenes. The read-only compact overview shows initial serialized configuration, not progress loaded from PlayerPrefs.

Ordinary configuration editing does not implicitly save player progress. Explicit progress reset/delete controls remain destructive. Do not change IDs or LevelDataKey to reset a test. Use an isolated preference namespace and copied scenes. See [Title Scene: levels](https://denvzla-estudio.gitbook.io/infinite-runner-engine-3d/title-scene) and [known limits](https://denvzla-estudio.gitbook.io/infinite-runner-engine-3d/attention).
