BLOCK BRAWL 3D
PLAYER SUPPORT
Free validation release · support does not require a paid plan
Start or resume a fight
Choose a mode on Home. On desktop, select START OR RESUME FIGHT and allow the arena to capture the pointer. Press H to return Home. Touch devices use the on-screen joystick, JUMP, DASH, and USE controls. Friend invites use the browser share sheet when available, then clipboard copy, and otherwise show a selectable game link for manual copy.
Local saves and recovery
Player names, appearance, friends, arena choice, motion preference, and career progress currently stay in this browser. Use EXPORT on Home to keep a JSON backup. Use RESTORE to load that backup. Clearing browser storage, using private browsing, or changing devices can remove data that was not exported.
Account and data controls
Cloud storage is not active in this validation release. The Account screen is a prepared foundation and will report that storage is paused. When cloud records are enabled, that screen can download or permanently delete the authenticated account record.
Accessibility help
The game supports keyboard controls, visible focus, reduced motion, touch input, and remapped keyboard aiming with I/J/K/L. If a barrier prevents play or data access, describe the device, browser, control method, and screen where it occurs.
Local diagnostics
Download a local diagnostics file to capture the app version, browser description, WebGL availability, input capability, and reduced-motion setting. The file is created only when you select the button, is not uploaded automatically, and does not include your player name, saves, friends, account record, cookies, or payment data. Review it before sharing.
Graphics troubleshooting
If the arena cannot start or stops rendering, update the browser, enable hardware acceleration, close other graphics-heavy tabs, and reload. Your device save remains in this browser. If the problem continues, download the local diagnostics file above and attach it to your support email after reviewing its contents.
Billing safety
No checkout, subscription, trial, renewal, or payment collection is active. Block Brawl support will not ask for card numbers, bank credentials, passwords, or authentication codes.
Contact and security reports
Send ordinary support and accessibility questions to support@nextstarai.com. Include the browser and device, what you expected, what happened, reproduction steps, and any support reference shown by the app. Do not email passwords, authentication codes, payment information, or sensitive personal data. Report security vulnerabilities privately to the same address with SECURITY in the subject or through the repository's private vulnerability-reporting form. Do not post exploitable details publicly.
