Galactic Math 2.0 is everything that landed between the March launch and today: a second game, a new setup flow, a real feedback pipeline, and a long list of fixes to make it easier and more fun to use.

Highlights

👾 Alien Invasion — a second game

A full arcade mode alongside the quiz: steer a ship with keyboard, touch or trackpad, dock into question rings, dodge comets and obstacles, and clear the aliens before they reach Earth. Along the way it picked up a radar view, a low-fuel warning, docking and gate-entry sounds, ten rotating facts per planet, a neon Earth with real continent geography, mobile support, and a Sneak Attack / Invasion / Chaos difficulty pick (5 / 10 / 25 aliens). (#74, #79, #81, #82, #89, #91–#95, #99, #101, #113, #119, #121, #122)

Alien Invasion

🚀 The Flight Deck setup

The single long setup card is now a five-step deck — Numbers → Math → Game → Options → Launch — with a flight-path stepper, Back / Next in fixed slots, and a Mission Briefing that lists every choice before Begin Mission. Galactic Math and Alien Invasion are equal game cards. (#135)

🎉 Celebrations and sound

Ring shockwave celebration in Standard and Hyperspace, comet streaks in Kessel Run, a launch sound and Begin Mission fill animation, an abort-mission sound, distinct sounds for enabling timed modes, and a sound on the feedback transmit button. (#50, #64, #67, #68, #69, #102)

🧮 Quiz interaction design improved

Multi-operation sessions are now composed correctly; unanswered questions show Skipped instead of null; input is blocked once the Hyperspace timer ends; Hyperspace and Kessel Run timers run on the wall clock so switching tabs no longer pauses them; an Abort Mission button on the quiz screen; operation modes can be reset or fully deselected with validation on start; clicking the banner returns to setup. (#33, #34, #36, #62, #70, #77, #78, #129)

💬 Feedback pipeline optimized and secured

The feedback page POSTs to a Cloudflare Worker that validates, rate-limits by IP, generates a title with Workers AI, and opens a GitHub issue in this repo. Since then: observability logging, automatic detection when Cloudflare retires a model, enforced allowed origins, a shared rate limiter, an AI prompt hardened against injection, and the Your Name field removed. (#37, #42, #43, #53, #55, #61, #123, #127, #130, #133)

🔒 Security and performance

Per-resource Content-Security-Policy directives plus X-Frame-Options, nosniff, Referrer-Policy and Permissions-Policy; a security.txt; two hardening passes; the starfield rewritten to stop draining tablet batteries and to honor prefers-reduced-motion; ~2.8 MB of unreferenced images removed and the OG image resized. (#83, #96, #100, #128, #131, #132)

📱 Mobile

Number grid overflow, the off-screen theme button, spacing and layout passes for small screens. (#30, #31, #32, #56, #110)

🪐 A legit website domain

The site moved to galacticmath.app, with a new planet logo for favicons and the share image, Open Graph / Twitter Card tags, and LinkedIn preview fixes. (#29, #80, #97, #106, #107, #109)

📚 Docs and workflow

A docs/ folder describing every part of the app, a docs audit, CLAUDE.md brought back in line with the codebase, hover explainers on the How It Works page, a GitHub link in the footer, and a written release process. (#51, #71, #73, #108, #134, #136)
