READY FOR FLIGHT
Choose your aircraft. Build it after every wave.
VANGUARDCAMPAIGN · STANDARD
Flight guide · Aegis, Focus & Pulse
Hull = health. At 0 Hull, the flight ends.
Aegis = automatic protection. Each charge blocks one hit before Hull takes damage. Starts at 0; choose Aegis Capacitor to gain it. Refills at the start of each wave.
Focus = precise steering. Tap to toggle half-speed movement for narrow gaps. Free to use; no charges. Extra damage requires the Deadeye Lens upgrade.
Pulse = emergency bomb. Tap to clear enemy bullets, damage enemies that have entered the field, and gain brief protection. Starts with 2 charges; each use spends 1, with a 2-second cooldown.
Threat signals: A shrinking amber ring means an enemy is about to fire. Amber brackets mark up to two priority threats. Amber bullets are hostile; cyan gunshots are yours.
Upgrades: Passive and automatic effects need no button. Deadeye Lens works with Focus; Pulse Reserve improves your bomb. One-time rewards apply when picked.

To our testers
Thank you for flying, finding bugs and helping shape CIRRAVORN.
CIRRAVORN tester edition · Updated 8 September 2026
What the game saves
This version stores your nickname, selected aircraft, settings, scores and campaign checkpoint in this browser. A previous save is also kept for recovery. A random run identifier helps avoid duplicate local scores.
Where it stays
The game does not upload your profile or scores to a leaderboard server. Rankings are local. Saves belong to the browser and site address you use; they do not automatically sync between devices, browsers or site addresses.
Your choices
Use a nickname instead of personal information. In Settings, you can export your progress or import a backup. An exported JSON file includes your nickname, progress, scores and settings. Only share it with people you trust.
To remove your local profile and recovery save, clear this site's website data in your browser settings, then reload the game. This removes progress from that browser. Downloaded backups remain until you delete those files. Private browsing or browser cleanup can also remove your saves.
Hosting & connections
Loading the website sends network requests to our hosting providers, OpenAI Sites and Cloudflare. They may process technical request data such as your IP address and browser information to deliver and protect the site. Their services have separate privacy policies.

This version
The game code includes no advertising SDK, analytics tracker, purchase system or player account system. It uses browser local storage for saves, rather than game-owned tracking cookies. These statements cover the game itself; hosting services may use their own cookies or security features.
