Zapper is an action-adventure game where you play as a cricket named Zapper on a mission to save his brother. The game takes place across six worlds, each divided into 20 levels. As you progress, you'll need to avoid hazards and capture eggs while encountering both friends and enemies that will either help or hinder your journey towards stopping the diabolical Maggie, a magpie with a penchant for nest-building.
The gameplay is all about navigating through these levels, using Zapper 's electric antennae to zap opponents and collect points. You can move in four directions, climb up walls and trees, and use your antennae to stun enemies. The ultimate goal is to reach the end of each level and progress through the six worlds, all while keeping an eye out for Maggie's nefarious plans.
