What changed in this build

Score is now tied to survival time, with speed stepping up every 15 points and spawn gaps tightening as the run deepens. Flying obstacles begin appearing around score 20, tall columns join later, and every 20 score or so the game has a chance to send in a shield or slow-mo pickup as long as no effect is already active.

• Distance is the main score engine here: the counter rises with time, not with coin pickups. Coins matter, but they are bonus value layered on top of survival.
• Difficulty ramps in steps. Every 15 score the run gets faster and the spawn rhythm tightens, then tougher obstacle types begin appearing once the score reaches the later thresholds.

• Treat the second jump as correction budget, not as free style. The cleanest runs are the ones where the first jump solves the obstacle and the second jump only saves awkward spacing.
• Pickups are strongest when planned early. Shield and slow-mo are worth bending for only when the route stays stable after the collection.
