CLASSIC ARCADE BENCHMARK 07: Strike Vector. Build a complete playable browser arcade game as one self-contained index.html using Three.js. Make an original bowling-inspired arcade score attack with a visible launch area, lane, rolling ball, target formations, collision outcomes, keyboard and touch controls, score/local high score, end state, and instant restart. The player must aim, set power, release, and see why a roll cleared, glanced, or failed. Include a safe central formation, a narrow high-value route, a condition-changing target, and a recovery opportunity. Add visible lane conditions that alter the best route, plus a momentum bank earned through controlled clears and special route hits. Spending momentum should stabilise a hard roll, reveal a route, unlock a target formation, or grant a valuable choice. Escalate through formations and lane decisions, not tiny impossible targets. Theme, pins or target forms, venue, ball design, music, and art direction are open. No external asset pack. Submit final index.html only, not a mockup or explanation. It must run in a modern browser with no build step.
