I'm a Demon King, But I Can Only Create Slimes ~Idle Management of a Time-Loop Demon Army~

You are the secretary to the Demon Lord, whose only power is summoning slimes. Unable to cast dark magic or perform physical attacks, your role is to endlessly spawn slimes from the castle gates and defend against advancing heroes intent on defeating your master. This is an idle defense game designed to be enjoyed in a corner of your desktop. The core mechanic revolves around managing slime production—breeding slimes, upgrading their abilities, combining special variants with poison or bleeding effects, and overwhelming heroes through sheer volume. No quick reflexes or complex controls required; simply watch as masses of slimes overwhelm your enemies. The game features persistent upgrades that carry between battles, wave-based loops that escalate in difficulty after defeating legendary heroes, and a desktop companion mode allowing passive progression while you work. Offline growth continues even when the game is closed, rewarding you with accumulated gains upon return.
