Specific Strategies
During the second stage, Queen Slime follows a fairly predictable pattern. The player can run back and forth on a long platform, jumping over projectiles, and Queen Slime will remain at roughly the same height the entire time, making targeting easier.

Be careful if you reverse directions as all previously summoned slimes will still be alive.
