1000 M is the third subchapter of Chapter 7: The Summit B-Side in Celeste. The subchapter resembles Chapter 2 and uses that chapter's mechanics in new challenges. In the final room, after reaching the purple orb at the end, the player will be taken to the next subchapter.
Gameplay[]
This subchapter will have a few rooms with no floors or floors of spikes where the player must keep themself in the air with space blocks and their dash restoration. Space block jumps are mandatory to complete some rooms here, so any player who hasn't completed Chapter 2's B-Side should go back and learn this technique before attempting this subchapter.
Strategies[]
Room 1
From the start of the room, you can jump and dash straight right into the first space block and space block jump out of it. Next, after falling for a bit, you should dash straight right, then up-right into the corner of the next space block to enter it diagonally. Shortly after exiting this space block, dash down-right to enter the next space block, then after exiting it dash straight right and up-right again into another space block. Move to the right after popping out of this space block to fall between the spiked floors, then dash straight right and up-right once again into the next space block. Do two dashes straight to the right after exiting this space block, then fall to the left to hit the spring and be bounced right with both dashes restored. Dash straight up and grab the wall to the left, then jump off to the right and dash up again, then climb out of the room. A player who is adept at wall bounces can actually wall bounce off using their first straight up dash to reach the end quicker.
Room 2
Walk into the spring to be bounced up, then dash straight up and straight right into the space block. Quickly dash straight right again after popping out of the space block to enter another one, then you need to quickly dash straight down and straight right to avoid spikes and enter another space block. After a space block jump out of the previous space block, you'll arrive at a pair of space blocks separated by a platform with spikes all over it. There are two methods to finish the room from here. For the first method, you can dash right into the lower space block and space block jump out of it, then dash straight up and straight left, then dash straight up to through the room transition. The second method, however, is much easier. Grab the space block instead of dashing into it, then jump off of it to the left and you can dash straight up twice to reach the end without having to go around at all.
Room 3
You'll need to make dashes into fairly small space blocks in this room multiple times in succession to make it to the end. Dash straight up from the start of the room, then dash right once and grab the left wall nearby. Jump off of it to the right and dash straight up into a space block to restore both of your dashes. Fall to the right after popping out, then fall a bit before dashing straight right and straight up into another small space block. Fall to the right again, carefully avoiding the bit of spikes at the right, then again dash straight right and straight up into yet another small space block. You'll then be able to be bounced by a spring, after which you need to fall carefully between some spikes below before dashing straight right and straight up into a space block again. Wait a bit after popping out of this one, then fall to the left a bit, then dash straight right and straight up into the last space block of the room.
Room 4
Dash into the first space block and jump out of it to get far to the right, then you can dash straight up twice to reach the purple orb. After you're thrown up, dash into the space block to the left and space block jump out of it, then dash straight up and begin to climb the corridor. Once you're lined up with the next space block, dash to the right and space block jump, then dash to the right again into the purple orb. Dash straight up after you regain control, then straight left a bit after into another space block which you should space block jump to the left from followed shortly after by a diagonally up-left dash. You'll then reach a bit of the left wall, and from here you can jump to the right and dash straight right and space block jump again, then dash up-right to reach a bit of the right wall above. Jump to the left and dash left here, then space block jump and quickly dash straight up and straight right into another space block. Space block jump again and dash straight up shortly after, then dash straight left into the final space block. You can jump out of this space block and dash straight up to reach the top of the room, where you can go over to the spring and bounce on it, then you can dash straight up into the purple orb and be taken to the next subchapter.
