Play without signing in

The game is public and free to play. You do not need an account. We do not save a run in progress.

Game analytics

We use our own Sites-hosted counters, without Google Analytics, advertising pixels or analytics cookies. We count page loads, game starts, waves started and cleared, tower choices and upgrades, boss encounters, wins, losses and sharing-button use. These are aggregate daily totals. We do not store IP addresses, emails, full referrer URLs or browsing histories in the analytics database.

Random delivery receipt identifiers prevent duplicate event batches. They are removed after seven days and are not used to identify visitors across visits. Browser-blocked or repeated events can affect the counts.

Optional accounts and scores

ChatGPT manages optional sign-in. For a submitted high score, we store a site-specific account identifier, the public nickname you choose, points, round reached, cleared rounds, defeated enemies, remaining Palace health and submission time. Your email and account name are not published or stored in the score database. The leaderboard shows the nickname and game result. Keep personal information out of your nickname.

Your best submitted run per difficulty season is retained. Earlier seasons remain separate. Short-lived score-run records are deleted after seven days. Scores are community submissions checked for basic plausibility, not independently verified competitive records.

Browser storage

A service worker caches the public game, artwork, icons and music for offline play. It does not cache account, score, sign-in or owner-dashboard requests. Cached game files are replaced when a new release activates. You can remove them through your browser site-data settings.

Your best local result uses browser local storage and can be removed by clearing this site's data. An owner dashboard access key may be kept in session storage for that tab. Account sign-in uses the hosting platform's session cookies.

Sharing and hosting

Sharing buttons open the service you choose. No Facebook SDK, tracking pixel or embedded social feed loads in the game. The host and sign-in provider may process technical request data under their own policies. Music and game graphics are served directly with the game.
