Parasite Slime

Important Notice: Change in How to Play

Due to Itch.io's 500MB file size limit for "in-browser play" (HTML5) games, version V0.4.0 (which includes the full Chapter 3) now exceeds this limit.

Therefore, starting from V0.4.0, the game no longer supports in-browser play. Please download the game to your computer to run it.

Thank you for your understanding and support!

Game Description (for itch.io)

You are not human.

You are an amorphous, primal entity—a parasitic slime. Your survival depends on a fragile, intimate, and dangerous bond with the humans you choose as hosts. Infiltrate their lives, control their bodies, and weave your way through a society that must never know you exist.

About the Game

Take control of unsuspecting hosts, from a diligent office worker trying to survive a city-wide lockdown to the key figures in a mysterious rural village. Each host offers a unique window into the human world and a new set of challenges.

As the parasite, you must carefully manage your host's Stamina and Sanity. Push them too hard, and their mind might break, offering you a chance for permanent possession. But be cautious—every action has consequences. Careless behavior will raise Suspicion, and if you are discovered, it's game over.

Features 特性

• Possess Multiple Hosts: Take over the lives of several unique characters, each with their own story, relationships, and daily routines to manage.

• Deep Parasite System: Juggle your host's Stamina and Sanity while keeping your own Suspicion level low. Will you be a subtle manipulator or a ravenous possessor?

• Dual Skill Trees: Evolve your core slime abilities that apply to all hosts, and invest in host-specific "Erosion" skills to unlock powerful and unique interactions.

• Dynamic Relationships: Interact with a cast of NPCs. Build favorability to unlock new story paths, crucial information, and special intimate events.

• Shift Your Strategy: Detach from your host to move freely as a slime, exploring new areas and planning your next move at the cost of increased risk.

• A Mature, Story-Driven Experience: Delve into a dark, unfolding narrative with adult themes and meaningful choices that impact the outcome.
