Cassette Tapes are special objects, found in the A-Sides of chapters 1 through 8, which unlock each chapter's respective B-Side. As such, they are a prerequisite to unlocking a chapter's given red crystal heart, and all of them must be collected before the C-Sides are unlocked. Cassette Tapes are always found in a Cassette Tape Room, which features Cassette Blocks and an 8-bit remix of the chapter's given music. Collecting a Cassette Tape will always lead to Madeline being transported, via bubble, back to the beginning of the room she came from (minus 8A, where she gets transported to the end instead).
Locations of Cassette Tapes[edit | edit source]
The cassette is hidden at the beginning of the Chasm checkpoint. In order to find it, go past the zipper on the left to reach an optional area, and then stand on the next zipper and launch yourself upwards. It will take you to a berry room, however there's a hole in the wall to the left, which is covered by another zip mover. Grab it to get it out of the way, and the cassette room can be found past the gap in the wall.
It's found in the Start checkpoint. Go down-right to activate the dream blocks, and after coming back to the "hub" section, fall to the very bottom and dash through the dream block that can be seen in the ground.
The cassette can be found in Elevator Shaft. Get to the key room and the entrance will be visible on the very far left on the room. It's indicated by a lightbeam coming out of the hole.
The cassette can be fairly early in the Shrine checkpoint. After passing through the touch switch room, the next room has a hidden entrance that can be seen in the top-left corner. Use the cloud to reach this height, and run to the left of the berry room which takes you to another hidden area with the tape in it.
It's found in the Hollows checkpoint, behind a breakable wall on the bottom-left side. You need to take a Kevin block to the bottom and let it break the wall. It will open the way to the tape room.
It can be found in the 5th room of 1500m by going through an optional path at the top. It's easily noticeable, however the player has to dodge a moving dust bunny that blocks the pathway.
Core[edit | edit source]
The Cassette Tape room is right at the end, and you will pass by it on your way to the Crystal Heart at the end of the level. No further instructions are necessary; go ahead and finish Core, more specifically, the section where lava and ice goes up and down in a sandwich-like pattern.
