Help me Cleaner Sama!: I Got Isekai'd to Clean Monster Girl Basements (2026): Puzzle, Indie. Developed by NyakuGames. Available on PC (Microsoft Windows).

This is a comedic fantasy puzzle game that follows an overworked cleaner transported to another world and tasked with clearing dangerous basements for a cast of eccentric monster girls. The story blends absurd humor and visual novel-style dialogue with satire about work, responsibility, and everyday frustrations. Gameplay focuses on grid-based, turn-based puzzles where players manage limited movement, avoid hazards, and solve stage-specific challenges that vary by character. The game also includes mature themes, unlockable animated scenes, and a gallery mode.

A poor street cleaner, exhausted from overtime, is sucked into a portal and finds himself before a self-centered goddess, who entrusts him with a task as absurd as it is inevitable: to clean out the cellars of the Monster Girls who inhabit that world.
