Terms of Service

Last updated: 7 November 2026

Playing

Free, with no purchases, no paywall and no sign-up. Start from stage one. Firing is automatic; move with the arrow keys or WASD, or drag on a phone. Three primary weapons switch on the fly, and the run ends when bombs and lives are gone. There is no single correct line: hugging the bullets reaches a boss sooner, but grazing scores nothing, so a cautious run also clears.

Ownership

The name, the code, the tuning, the copy and the look belong to GameStrategists. Links, recordings, streams, walkthroughs and a few quoted screenshots are welcome; please do not mirror the whole site, and do not claim you made it. Third-party names and trademarks mentioned belong to their respective owners.

Scores and saves

Your best score and the furthest stage are written only in this device's browser, under the namespace gs:tieyi:. There is no server copy, so we cannot restore, migrate or verify a record for you.

Availability

The game is provided as is, with no promise that it will never go down. Maintenance, deployments or a hosting fault can make the page unreachable for a while, and frame rate varies between browsers and devices.

Third parties

The page loads the Google AdSense script to cover the domain and hosting. There are no ad slots inside the game frame and ads never cover the controls. How data is handled is set out in the privacy policy.

Changes

Tuning, levels and page copy may keep changing, and those changes are logged on the hub site. If these terms change in substance, the date at the top of this page changes with them.
