Celeste: Chapter 1's B-Side Course (Red Heart)
7The main Chapters that you playthrough in this game are called A-Sides. If you can find an Cassette Tape in each of them, you can unlock their B-Side courses.
----------
In these levels, B-Sides are remixes of A-Sides. They have much harder layouts that are based on the A-Side's elements, and have actual remixes of their songs done by different people besides Lena Raine.
B-Side levels are entirely obstacle course challenges. You don't have to worry about collecting Strawberries or anything else here. All you have to do is memorize the layout and use all of the skills that you know and learned to get Madeline to the end.
At every end of a B-Side, the last room will use those same, beat-based blue and pink platforms that you had to go through on the A-Side to get B-Side's Cassette Tape to begin with.
At the end of this room, you will find a Red Crystal Heart. Just dash into it, and it's yours! If you don't have a dash, just tap the Heart to regain one, and THEN dash into it!
----------
I will try to beat each and every Chapter's B-Side before I move on to the next A-Side, no matter how many times I have to die to get it done!
