Celeste Season 5 Release date & what we know

1. Start

Start is the first subchapter of Chapter 5: Mirror Temple in Celeste. The subchapter starts with Madeline and Theo examining the entrance to a temple before venturing in. Madeline is unsure about entering, but Theo is feeling adventurous to post pictures of the temple to his InstaPix account. In the subchapter, the player will have many paths to cross to eventually find the key which gives further access to a dark room which is locked off that leads to the next subchapter. A few of Chapter 5's gimmicks are introduced here including swap blocks, red bubbles, blue torches, dash switches, temple gates, and blades. In the third room of the subchapter, Madeline can find Theo's phone lying on the floor at the top, implying he's gone missing.

2. Depths

Depths is the second subchapter of Chapter 5: Mirror Temple in Celeste. The subchapter starts with Madeline finding Theo inside of a mirror, with both being confused on how it happened. After continuing forward through the subchapter, the player will eventually come across a giant mirror which, after activating it by hitting 2 dash switches, will suck Madeline into a dream. There will then be a section where the player plays as a Seeker to kill Madeline in this dream and wake her up, ending the subchapter. Aside from informally introducing Seekers, red walls, and barriers via the Seeker dream, this subchapter also introduces yellow torches. The Crystal Heart of Chapter 5 and the Cassette to unlock Chapter 5's B-Side can both be obtained in this subchapter.

4. Search

Search is the fourth subchapter of Chapter 5: Mirror Temple in Celeste. The subchapter will task the player with getting keys from across various paths to advance past a floor of corrupted spikes using a red bubble. In the first room of the subchapter, Madeline will be scared and confused at how she will save Theo before then relieving herself. A room to preview Theo trapped in a crystal is located above the second room of the subchapter and Madeline will be able to have a conversation with Theo here behind some crystals.

5. Rescue
