2000 M is the fifth subchapter of Chapter 7: The Summit in Celeste. The subchapter brings back the mechanics of Chapter 4 and utilizes them in new ways. In the final room of the subchapter, Madeline and Badeline will talk to each other while being boosted up from the last purple orb, then combine back together to enter the next subchapter.
Gameplay[]
The double mid-air dash granted in this chapter will shake up interactions with quite a few of the objects in this subchapter. Remember that wind doesn't affect Madeline's speed while dashing and that green bubbles grant back both dashes as these will be needed for many rooms. The sixth and seventh rooms of the subchapter will be long rooms based around guided platforms and triggered platforms respectively. For the former, moving the guided platform up and down so it can pass through gaps of crystals and not break on a wall will be required. Additionally, the player will need to move a triggered platform at the end out of the way, allowing the guided platform to continue to the end of the room. For the latter, the triggered platform moves straight up for the whole room and the player is just tasked with moving out of the way of spikes with careful stalling with both of their dashes.
The diamond piece of the Crystal Heart of this chapter is in a very peculiar location which first requires the player to go left of the second room of the subchapter. This leads to a seemingly pointless room, however the left transition of this room will lead to another room. To get there, a hidden passage within the gap right above the crystal spikes can be dashed into, allowing the player to get the distance needed to reach the left side. If the player is adept at wavedashing, they can do that from the right of the crystal spikes and get to the left side that way. In the following room to the left, the player needs to jump and do a dash to the left just underneath the long protrusion in the ceiling, then do an upward dash to climb this protrusion from the left side at the top, do a jump to the left and a hidden area up above will let Madeline get both dashed back. Next, slide down the ledge from this breather area and hold left. A diagonally up-left dash and then a well-timed straight up dash can get the player on the left side of the next dip in the ceiling and by climbing up it, the area with the diamond piece is accessed. From there a simple area will take Madeline back to the first detour room.
Strawberries[]
There are 8 Strawberries found in this subchapter.
Berry 1
Above the second room of the subchapter, a small gap in the ceiling is seen on the left side. By going into the left screen transition and dashing up back to the second room, you can get into this gap. In it is a room filled with some pink clouds and crystals. Jump right after you land on the pink clouds to not be bounced into the crystals and you can easily make it to the end of this room where the Strawberry floats.
Berry 2
Found in the fifth room of the subchapter, this Strawberry floats at the far-right side below the ending bridge. To get to it, you'll need to get to the left ledge just below and dash straight right, then straight up and hold onto the wall. Climb high and wait for a snowball to come at you, then jump onto it or just let it hit you from below and then dash straight right twice to then climb the right wall and collect this berry.
Berry 3
Found in the seventh room of the subchapter, this is one of the trickiest berries to collect in the game. Ride the triggered platform up for a bit and then after passing the disappearing platform, you'll need to precisely stall in the air and eventually dash into the dash crystal at the same time the triggered platform is there. Jump off and then dash straight up into the Strawberry, then repeat this process again when the triggered platform arrives. Finally, you'll need to do a dash straight up and then straight to the right to land back on the triggered platform and, by finishing the room, collect the Strawberry.
Berry 4
In the eighth room of the subchapter, you can go to the left transition to find a room with this Winged Strawberry. By jumping from the right ledge, you can make it the left floating platform. Jump to the right and climb to the top of the right floating platform before jumping all the way to the left. With a straight left dash, then a quick straight up dash, you can catch the Winged Strawberry before it flies away.
Berry 5
In the room of the previous Strawberry, a smashable wall is seen on the ceiling which leads to another room with a Strawberry. However, this is Strawberry 6, not 5. Above the room is yet another secret berry room, accessed by leading the guided platform at the start to the left and riding it to the top transition of the screen. The room that follows is a seeded Strawberry challenge. Like seen in Chapter 4's seeded Strawberry, once you collect a seed the wind will start to blow to the left. Go to the top-right of the screen and dash into the nearby seed. Fall down into the dash crystal, where you'll then diagonally dash up-left and jump constantly up the wall (in order to save stamina) and at the top, move right to collect the next seed. Jump off this wall and onto the right side of the floating platform, then jump over it and go to the left to climb the left wall into the final seed.
Berry 6
This berry is located below the room of the previous Strawberry, as well as above the room of Strawberry 4. In this room you need to first approach the guided platform by doing a straight up dash and then a straight right dash. Guide this guided platform to the right as it goes up and fall into the green bubble. Direct that green bubble up-right and then a straight up and straight right dash can get you to the other green bubble. For this one, launch it straight upward and then fall down and dash right in the gap of the crystals to reach the berry.
Berry 7
Found in the ninth room of the subchapter, this Strawberry will be very straightforward to collect. As you're being carried to the right by the wind, you can see this Strawberry in a small gap of crystals, so dash straight into it and then up-right to get into the green bubble and complete the room normally from there.
Berry 8
Found in the eleventh room of the subchapter, this Strawberry will have a familiar method of reaching it as some prior subchapters. At the end of the room where the purple orb would take you to the next subchapter, avoid the purple orb and dash to the right underneath it into the suspicious cracked wall with no crystals on it. Hidden in this area is a Strawberry.
