## Overview
Science Monster: Grafted Heart is a unique organ-building survival roguelite developed and published by JIELIN. Instead of traditional classes or weapons, players graft living organs into a mutating body to survive. Each organ possesses distinct characteristics, including shape, weight, blood demand, heat output, and unique attack behaviors, contributing to a dynamic combat system.

## Highlights
*   **Organ Grafting System:** Players build their combat capabilities by grafting various living weapons and support organs into a mutating body, rather than selecting classes or equipping traditional gear.
*   **Dynamic Combat:** Organs like bone cannons, frost glands, acid glands, and parasite wombs offer diverse offensive and defensive capabilities, with support organs and mutations further altering combat effectiveness.
*   **Roguelite Survival:** The core gameplay loop involves moving, surviving, and collecting temporary catalysts to empower equipped organs, creating unique builds in each run.

## Who It's For
This game is for players who enjoy roguelite experiences with a strong emphasis on strategic build-crafting and emergent gameplay. Fans of top-down shooters and bullet hell games looking for a fresh take on combat mechanics will find the organ-grafting system particularly appealing.
