Wall Them In — Don't Wall Them Out

Every tower you place blocks the path, but you can never fully seal it

🧩

Maze-Building Defense

Place towers to build a maze that forces enemies the long way round. The game blocks any placement that would fully seal off their path — you can slow them, never stop them cold.

🎮

Single Player — Free

Defend the field solo. 300 starting gold, 20 lives, and waves that escalate the longer you hold. No purchase needed, ever.

🤝

2-Player Co-op

One shared battlefield, one shared gold pool — plan your maze together, same device, pass-and-play or side by side.
