Independent distribution
This is not an official release from the upstream PC team. Original authors retain their rights. Upstream names identify the game on which this edition is based and do not imply endorsement. Contact C60 Limited about Android packaging, controls, privacy or Play distribution.
Play, saves and optional features
The game is a single-player, turn-based survival sandbox. Core play works offline. Saves are stored on your device; this edition provides no publisher account or cloud-save service. Use the in-game Save command before ending a session. Uninstalling or clearing storage can remove saved worlds.
Quantum backups are experimental, off by default and can use additional storage. A rewind restores the complete saved world, including progress of other survivors in that world. It is not a guarantee against lost progress.
Advertising
The AdMob edition includes optional rewarded offers and optional sleep-break interstitials with a 30-minute foreground-play interval. It has no banner or app-open ads and no in-app purchases. Rewards are delivered after the advertising SDK reports an earned reward; unavailable or failed ads do not prevent normal gameplay. Ad availability is controlled by Google.
Google's advertising and consent SDKs retain their own terms; they are excluded from the separate FOSS build. Their privacy practices and player controls are described in the privacy policy.
Warranty and support
The open-source components are supplied with the warranty and liability provisions in their respective licenses. This page does not exclude any consumer right that cannot lawfully be excluded. Support is available at support@bellrope.app; no paid support or service-level agreement is offered.
