Neon Spindle

Neon Spindle has exactly one control — hold to draw in, release to fling. Every upgrade, enemy and boss is designed against that single input, which is why there is no tutorial screen anywhere in the build.

Runs are tuned to land between 80 and 140 seconds. We instrument run length rather than session length, because the thing that keeps a player is finishing a run, not opening the app.

Liveops is a weekly seeded rotation: one mutator, one leaderboard, no timers and no energy. We turned down an offer to add a rewarded-video gate on continues and the retention curve stayed flat, so it stayed out.
