Momentum

A meter with four tiers, CALM, HOT, WILD and FEVER, that multiplies the score.

Momentum (0-100) rises with every hit (+1.5) and with chains, leaks slowly over time (faster the higher it is) and drops with escapes. It persists from one chain to the next.

Tiers: CALM below 20, HOT from 20 (score x1.25), WILD from 48 (x1.6), FEVER from 78 (x2.2). A tier is kept until Momentum falls clearly below its entry (13 / 38 / 62), so it does not flicker.

Higher tiers also light up the fair: more lamps, a louder crowd and extra music layers.
