Boss[edit]
At the end of the level is a large enemy. It is large and will normally advance slowly. As it approaches or as you near the edge of the arena, it will charge forward. Leap over it using the double jump.
This enemy is vulnerable to attacks on its head, either from the double jump or by shots. When it, it will retaliate with a volley of close-range attacks, dodged by running away.
When destroyed, the day is complete.
