8 hours, stats are tracked and persist.
Fixed flyer spawner failing to illuminate after spawning its first wave. Added in a visual indication of the build percent of a landed shooter. Fixed easy phase 11 exit conditions. Toned down easy phase 15. I am now tracking 10 stats, practice runs, true runs, best phase reached, run completions and best run time. Each tracked for both difficulties. These are accessible through a new stat screen reachable through the main menu. Whenever one of these stats would change, the game checks and saves the new stats. These stats persist across game launches.
