A continuous stream of enemies is spawning. Collect segments to grow stronger and deal with the enemies.
Approach scattered segments and grab them with your mouth. Press the right mouse button to attach the segment to the end of your body.
Different segments have different abilities. Three identical segments in a row can combine into a more powerful segment.
If needed, press the left mouse button to shoot the segment held in your mouth and insert it into the middle of your body to assist with combination.
Be mindful of your length—a body that is too long may make it harder to dodge enemy attacks.
