Heartbeat is the fourth and final subchapter of Chapter 8: Core B-Side in Celeste. The subchapter is split into two sections, with a rising ice/magma section in the first half and an ice/magma corridor section in the second half. At the end of the subchapter is a vertically wrapping room with cassette blocks. The red Crystal Heart to complete the B-Side can be found in this subchapter.
Gameplay[]
In the first section of this subchapter, rising ice/magma will force quick and precise movements to make it up each room in a timely manner. In the second section, ice/magma corridors will cover large horizontal rooms where the magma rises while the level is hot and ice will descend when the level is cold. In the last room of the chapter, the screen wrapping, low gravity room from the end of the A-Side returns with crystals all over, making it able to kill the player, and without Madeline's thoughts being present.
Strategies[]
Room 1
Run to the right and jump up to then dash diagonally up-right twice to grab the launching block at just above its midpoint, then fling yourself leftward with it. You'll reach a dash crystal, then from here dash straight up and straight left and start climbing the left wall. Jump to the right onto the launching blocks below, continuing to the right on them until you reach the spring on the wall with a dash crystal nearby. After being bounce left, fall a bit and then dash up-left twice to grab another launching block on its upper half. You'll be able to fall into a dash crystal on the right, so once you collect it you should dash straight up and straight left and ride the conveyor wall up to the end of the room.
Room 2
Walk left and jump up on the ledge, then jump up and dash straight up when the fire balls are on the left and right sides. Move right after flipping the hot/cold switch and bounce up on the ice ball on the right, then bounce on the other ice ball, then touch the right side of the bumper to the left to be bounce to the right. Dash up-right shortly after being bounced to land on an ice ball, then start moving left while bouncing on the ice balls until you can bounce up on the bumper, then move left to be bounced right off of the bumper to the left. Collect the dash crystal, then dash up-right and straight up to flip the hot/cold switch, then move right and ride up the conveyor wall.
Room 3
Jump to the spring on the left, then dash twice straight to the left and grab the wall. Climb up when a fire ball above just passes to slide up the conveyor wall, then do the same when the first fire ball above passes on the conveyor wall above. Jump to the right and dash up-right twice in order to reach the dash crystal being circled by some fire balls. From here, start dashing straight up while moving left and right accordingly to keep reaching dash crystals above until you reach the transition to the next room.
Room 4
This room will bring back the mechanics of previous chapters to help the player make it to the top. Jump to the left on the spring and move to the right to land on the traffic light block. Jump up when the traffic light block reaches the top, then dash straight up into the space block. Move to land on the moving platform, then jump and dash straight up to land on the moving platform above while avoiding fire balls. Jump and dash straight up again while avoiding fire balls to land on the white cloud, then do a big bounce up on it while moving to the left, then grab the swap block and climb onto it. Jump to the left to collect a dash crystal, then move back right. Dash straight down onto the swap block and jump as soon as it reaches the top for a big boost up, allowing you to move right and land on the angry platform. Dash straight down onto the angry platform and jump up as soon as it collides with the sides of the gap above, then move left to land on a launching block. Launch straight up to hit a dash crystal, then dash straight up twice to touch the purple orb, taking you to the next section.
Room 5
After arriving in the next section, go to the right and jump up to the ledge. Jump to the right and dash up-right over the launching block, then grab its right side and fling yourself to the right. Dash up-right into the hot/cold switch, then bounce on top of the bumpers nearby to the right. Touch the right side of the second bumper to be bounced far to the right, where you'll reach a shattering block or some of the floor where a hot/cold switch is nearby. Flip this switch, then make your way to the right to jump onto the launching block to the right, launching yourself to the right to an area with a hot/cold switch. Flip the switch, then walk off and touching the right side of the bumper below to be bounced to the right. Fall down after collecting the dash crystal, then dash up-right and up-left into the right of another bumper which will bounce you to the end of the room.
Room 6
Jump off the ledge and bounce on ice balls and use a dash to make it to the hot/cold switch and land on the launching block below. Try to aim yourself on the middle of the launching block where you would avoid the fire balls above, then dash up-right into the hot/cold switch. Bounce across the ice balls, with a large bounce to get over the ice barrier, then hit the hot/cold switch near the ice wall and start repeatedly grabbing and releasing the conveyor wall until the magma corridor rises far enough to allow you to go up and finish the room.
Room 7
Jump to the right onto the small bit of the floor, then jump right again and dash straight right to grab the conveyor wall. Ride up the conveyor wall a bit, then release and move to the left to flip the hot/cold switch and grab the bit of the wall on the left. Wait there a bit until the ice corridor is low enough for you to jump off, fall a bit, then dash up-right into the hot/cold switch to then grab the conveyor wall to the right. Ride up it briefly, then move left and grab the bit of the wall on the left. Jump to the right, flipping the hot/cold switch on the way, and aim to land on the bit of the wall below to the left of the dash crystal. Wall jump to the right and collect the dash crystal, then dash twice to the right and grab the conveyor wall, then you'll reach the end of the room.
Room 8
This room will not have any ice/magma corridors to worry about, instead it will be filled with a lot of magma barriers which need precise launching to get past. Land a bit to the right of the middle of the launching block below, then launch yourself up and move to the right to get past the first set of magma barriers. You'll then fall down with a launching block to the left and you should try to grab the highest point of this launching block as possible. Launch up from there and dash straight right, then fall down to grab the middle of the last launching block. Launch yourself to the right and dash straight up before colliding with the magma barriers, then climb up the ledge and finish the room.
Room 9
This will be the cassette block room of the chapter. Like in the A-Side, this final room will return dash controls to normal and have low gravity, with the most notable aspect being that the top and bottom of the screen will wrap around to each other. Make your way across the cassette blocks with simple jumps and dashes, then after the fourth cassette block you should dash straight right twice. Fall to the bottom of the screen to reach the top, then dash straight right twice through the gap of crystals to the right. Dash straight up to stall for a bit, then dash straight right when the blocks turn to blue to reach another dash crystal. Dash straight up twice to collect another dash crystal, then dash right if the pink cassette block to the right disappeared. After this, you'll slowly fall to land on a pink cassette block below, then jump right onto the blue block, then jump right again before the blocks turn to pink so you can bypass the blue cassette block to the right with spikes on it. Fall from the top of the screen to the right to collect the dash crystal, then try to stall a bit by dashing straight up before falling further right and passing the blue cassette block while the blocks are currently pink. After falling from the top, dash straight up to stall, then up-right to reach a dash crystal to the right when the blocks turn to pink. When you collect the dash crystal, dash straight up twice to wrap to the bottom and collect another dash crystal, then dash right or up-right to get on top of the anti-gravity platform. When the blocks turn to pink, jump up and dash straight up, then when the blocks turn to blue, dash straight right. From here, move right until you can touch the Crystal Heart, then dash into it to win the level.
