About this game
Grow Castle is an idle tower defense game where players defend their castle against waves of enemies. The core mechanic involves strategically upgrading towers and heroes to survive increasingly difficult challenges. Its appeal lies in its simple, satisfying progression and the ability to play in short, interruptible sessions.
