The game takes place in a futuristic, pixelated world overrun by zombies. The player's objective is to navigate through a maze of blocks, collecting resources and power-ups while avoiding the undead hordes.
The core mechanic revolves around the player's ability to swap blocks to create a path forward, using the resources gathered to unlock new block types and tools. The game becomes increasingly challenging as more zombies appear on the screen, and the player must strategically swap blocks to clear a path while minimizing contact with the zombies.
The game runs directly in the browser, requiring no download or registration. As the player progresses through the levels, the difficulty level increases, and new block types and challenges are introduced. The ultimate goal is to reach the end of each level without getting overwhelmed by the zombies, requiring the player to think strategically and plan ahead to succeed.
