The world of Interspace is an open 3D land filled with many different creatures. Some of them are friendly, while others are hostile. The only way to survive in this world is to eat other creatures and grow your own slither. However, you will need to be careful because some of the creatures are dangerous and can attack you. You can fight back and try to destroy the enemy by attacking them with your own slither. The more you eat, the bigger you will get. However, you will need to be careful because if your slither gets too big, you will die.
