I'm the Demon Lord, but I Can Only Make Slimes ~ Idle Management of the Respawning Demon Army ~

You are a Demon Lord with exactly one power: summoning slimes.

No fireballs. No dark magic. Just an endless stream of slimes, pouring out of your castle gate to meet the heroes marching in to kill you.

I'm the Demon Lord, but I Can Only Make Slimes is a desktop-companion idle defense game. Production is everything — grow your slime economy, mix in poison and bleed variants, and overwhelm each hero with sheer numbers as they crawl toward your throne room.

Features:

• Swarm-based idle defense — no unit placement, no micromanagement. Just keep producing, and watch your slimes swarm every hero that shows up.
• Permanent upgrades — every level you buy sticks around forever. Losing a run only costs you time, never your progress.
• Escalating wave loops — clear all hero tiers, defeat the climax boss, and start a tougher loop all over again. How many loops can you survive?

• Desktop companion mode — dock the battle on your desktop and let it run quietly while you work. Check in, produce more slimes, get back to it.
• Offline progress — come back later and your slime economy has kept growing while you were away.

No twitch reflexes required. Just build up your slime production, watch the numbers climb, and see how many loops of heroes your Demon Lord can outlast.
