Kinetic Stack

Steer hanging cargo, not a perfectly stable cursor. Heavy loads build sway faster; spend time settling or save your two brakes for the hardest crossings. Turn-based, not a real-time physics simulator. Each rail step sets sway to round(old sway÷2)+direction×mass, clamped to±6. The HUD previews both directions. Settle truncates half the sway toward zero. Brake sets sway0, twice only. Lower in the marked lane with absolute sway≤1; unsafe lowering loses. Correct deliveries reset sway. Four masses1,3,2,1 target lanes1,5,2,4;22actions. Wrong lane, rail edges, no-op settle/brake are free rejections. Undo restores all resources.
