A Former Hero Reincarnated as a Blue Slime Episode 3: Demon King Subjugation

A simulation game where you direct a half-beast girl to excavate through caves while managing a living ecosystem. Digging in areas rich with "magical essence" spawns slimes, which are hunted by centipedes, whose predation affects chicken populations—and thus the entire cave's balance. The core challenge is navigating these ecological shifts to safely extract magical stones. An expanded sequel that adds a demon king and hero to the ecosystem simulation, plus quality-of-life features like text auto-advance and skip functions.
