Backpack Castle Heroes

Backpack Castle Heroes is a Chrome extension game inspired by Tiny Castle Guardians. It delivers a casual yet strategic tower-defense experience where you defend your castle with auto-battles, smart unit placement, and wave after wave of challenges.

Key features include merging heroes and gear to power up, collecting cards to boost your build, and upgrading stats after each run. Each run presents three random upgrades, keeping the experience fresh as you tackle increasingly tougher waves. The game is designed for offline play and easy controls, but rewards thoughtful strategy and planning.
