Complete the levels with fireflies to catch them in a jar. Exchange the filled jars for valuable prizes. You have a limited time to catch fireflies.

The level where you can find fireflies is marked with a jar icon. Each level victory advances you by 1 point to filling the jar. You can fill 3 jars. The number of points for each jar is different.
