3000 M is the seventh and final subchapter of Chapter 7: The Summit in Celeste. The subchapter takes place on the summit of Celeste Mountain and contains a few very large rooms, separated by the newly introduced checkpoints. Most of the subchapter utilizes vertical wind which either pushes Madeline down or up, adjusting her gravity. The Crystal Heart of Chapter 7 can be obtained in this subchapter. At the end of the subchapter, Madeline will reach the peak of the mountain marked by a large red flag. Badeline will come out of her body to talk and realize she won't have her physical form after leaving the mountain, then they watch over the scenery and the chapter will end. After this, the game's credits will roll, and the player will be sent immediately to the Epilogue.
Gameplay[]
This subchapter will be quite difficult to get used to with the high gravity and low gravity coming from the vertical wind. At checkpoint 30 and 29 and 5-1, there will be no wind present. From checkpoints 28-20, the wind will blow downward and give a high gravity feel. From checkpoints 19-6, the wind will blow upward and give a low gravity feel. For most of the high gravity section, it will be quite simple involving getting around spikes and collecting dash crystals with usually some intermissions with disappearing platforms and/or springs. For the low gravity section, it will be much more open and generally a lot harder than the previous part. A few of the challenges will be very careful timing inbetween crystals as you move forward and fall or getting a lot of height with your dashes to get over crystals. At checkpoint 15, you need to stand right next to the crystals on the left, then do a jump and two diagonal up-right dashes to barely be able to grab the upper ledge. For checkpoint 14, it requires some careful climbing to be able to make it to the end with enough stamina to get to the top and jump over the crystal heap. Checkpoint 9 can be a nuisance as you need to do straight up dashes inbetween very small gaps in the layers of crystals while also needing to nudge yourself to the right without dashing diagonally. Checkpoints 4 and 3 will both make you use feathers to navigate through the crystals which might be tricky.
The Crystal Heart of this chapter is found in a room to the right of checkpoint 28. It will be inside a corridor guarded by crystals and all six jewels seen previously in the chapter will be slotted into the floor when collected. If all of the jewels are collected in a single run and the player makes it here, then the Crystal Heart will lower itself out of the crystals and become collectable.
Strawberries[]
There are 7 Strawberries found in this subchapter.
Berry 1
In the midst of checkpoint 26's platforming, this Strawberry can be seen floating under a platform. To get it, simply dash right into it and then straight up and touch the close-by dash crystal to continue onward and claim it.
Berry 2
At the end of checkpoint 24, a Strawberry is seen in a section to the left of where checkpoint 23 would be entered. From the disappearing platform below, jump to the left and dash leftward, then start to climb the wall. At the top of the wall, do a jump all the way to the right to get the Strawberry and get over the spikes, then do a dash to the right to land on the disappearing platform, then get to safety.
Berry 3
Near the start of checkpoint 21, this berry is seen above the normal path around some spikes. Bounce yourself off the spring and dash straight up to climb up the right side of the thin floating platform. Jump and dash into the Strawberry, then jump back left and jump over the floating platform and keep going left to make it back to the checkpoint and claim the berry.
Berry 4
To the left of checkpoint 18, a section with a lot of crystals and this Strawberry is found. There's a white cloud nearby, and to reach the berry, you'll need to do a full bounce up from this cloud and move left over the crystals. Using your two dashes, carefully time boosting yourself up and reaching the Strawberry while not touching the crystals. Afterward, fall into the dash crystal and make your way back to the cloud and you can safely claim the berry.
Berry 5
There's a Strawberry hovering to the bottom-right of checkpoint 16. It will be tricky but try to do a diagonal dash into the Strawberry after falling down from the bridge, then diagonally dash the other direction and wrap Madeline around the thin section of the wall to grab onto the left side and climb back up to safety.
Berry 6
To the left of checkpoint 15, beyond the tall wall of crystals, this berry is floating near the left wall. Do a full jump and then dash diagonally up-left over the crystals to make it to the Strawberry, then climb the wall and dash diagonally up-right back over the crystals.
Berry 7
This Strawberry is hovering above the main path of checkpoint 4, but it's recommended to make it to checkpoint 3 as a breather point before going for this berry. A feather will be needed to get to the area where this Strawberry is. If going for this berry while completing checkpoint 4, the feather utilized there can be brought upward to allow you to reach the small disappearing platform; if going for the berry after saving at checkpoint 3, the feather found right above can be brought down and to the left to give you access to the area. Jump up on the small disappearing platform and dash diagonally up-left over the block of crystals and grab the left side of the floating platform. From there, you can just jump to the disappearing platforms to the left and reach the Strawberry, then ride the feather below onward normally and you can claim the Strawberry when you land.
