# Organ Modification Use simple programming logic to build organ links. The skill building process is highly visualized and can be easily debugged. # Variable Organs The game includes hundreds of organs with different functions. Each organ can also be mutated to obtain additional affixes which can further generate more unpredictable changes. # Highly Replayability The difficulty of the game can be automatically adjusted to the progress of the game. After completing the main acts, there are still more difficult challenges, more modes and content to explore.
