Totemia: Cursed Marbles

This is a Zuma-style shooter: a chain of colored marbles crawls along a track toward a totem, and you fire marbles from the center to break up the chain by matching three or more of the same color before it reaches the end. It leans a bit more intense than the average marble-popper, the chain moves fast enough that hesitating over a shot costs you ground you don't get back. Forty-five levels get progressively less forgiving, and the last handful ask for genuinely precise aim.
