Quick answers
How do I unlock the level editor?
Clear all 21 levels in a single run starting from Level 1. Retries are fine — just don't start
mid-campaign. Once unlocked, it stays unlocked.
How is my score saved?
Best scores are stored locally on your device. The app has no accounts and makes no network
connections, so nothing syncs or leaves your device.
Does it cost anything / have ads?
No ads, no in-app purchases, no subscriptions.
