Chill Hills

"venture below zero"

Chill Hills is the sixth world that the player will encounter during a run. Pyro Droids fittingly do not appear at all, while Cryo Droids and their variants are much more common. Rapid-Fire Droid s and Switch Droid s make their debut, although Switch Droids are quite uncommon in Chill Hills.

Environment
Chill Hills resembles a polar area. It has a white snowy ground and gray walls that are tinted blue. Environmental objects include large ice spikes and igloos.

Chill Hills's environmental hazard is water. It is visually and functionally similar to the water found in Lush Jungle. However, there are water bodies in Chill Hills where some portions of the water are frozen while some portions are not.

Freeze/Melt buttons are fairly common here, with some rooms even having multiple buttons. The Candy Sword can still freeze the water here.

Ice spikes and water walls appear in Chill Hills. They are water and can be frozen and melted, but they do not deal any damage to the player if walked through while melted. When melted, they are translucent and do not collide with anything. However, when they are frozen, they become a solid obstacle. They can be used to block projectiles and in some cases stop Droids from chasing you (the walls).

Trivia

 * There is a room where an igloo spawns. Inside the igloo is a Friendly Droid.
 * Chill Hills is the last world to naturally take place during day time.
