Opal River Lantern

Opal River Lantern Gameplay:
Four shooters across the top loose darts downward. Your runner stays near the bottom and moves only sideways: press the screen and slide left or right.

You start with 3 hearts.

A needle costs 1 heart.
A bolt is thicker and slower, shows a longer aim line, and costs 2 hearts.
Every shot draws a faint aim line before it flies. Patterns are a straight drop, a dart drifted toward where you are standing, a pair from two shooters, a three-dart fan, and the occasional bolt. Higher scores make the volleys faster and the gaps shorter.
