What is 5b?:

The player starts the game as Book and moves through 53 levels though Evil Leafy. Match and Ice Cube are unlockable playable characters and are unlocked once they are met in the game. The game offers many platforming and puzzle challenges. In order to progress to the next level, all the playable characters must be in front of the exit door until it activates. Optionally, the player can collect one Win Token each level, most of which are in hidden or difficult to reach places. Beating the level with a Win Token will turn that level green on the level select screen. Win Tokens have no usage, but the number collected is tallied on the level select screen.

The Story:

Book starts out lost and forgetful of recent events. After realizing she is inside Evil Leafy, Book ventures out to find the other members of FreeSmart.

Book eventually finds Match trapped in a box in level 19 and asks if Match knows what is going on. Match recalls Pencil driving the FreeSmart Van into Evil Leafy's mouth. Match also remembers falling into her unpleasant box. Book and Match agree to find the other FreeSmarters.

Book and Match find the Hand-powered Recovery Center and the former figures it fell out of the FreeSmart Van.

Later, Match and Book enter a house in level 31. Inside, Book finds Lego Brick, but is first scared of him and thinks he is "an armless mutant Blocky". Lego Brick denies this and asks to be Book's friend. Book asks him "Where are we?" Lego Brick states that they are in Evil Leafy, along with thousands of other recommended characters. Lego Brick is confused at the fact that Evil Leafy ate Book and Match, but she reassures that they are fine. Lego Brick remains confused, Book says goodbye to carry on their adventure.

Book traps Lego Brick inside a box to activate a switch to complete a level. In the next level, Lego Brick turns mad, saying that Book trapped him inside a box. Book reassures her that it was only for desperate measures, but Lego Brick is unconvinced and punishes the two by forcing them to fall into his underground factory, teaching them not to mess with him.

Further into Lego Brick's dungeon, Book finds Ice Cube on an independent platform. Book asked her why she is in Lego Brick's Factory.

Ice Cube does not remember why she is in the dungeon but laments that if she had arms, she could pick up a nearby box to escape the dungeon. Fortunately, Book had arms, so she told her that she had arms. This made Icy happy. Book moves the box to the other low-hanging platforms, so Book, Match, and Ice Cube can continue the adventure.

The trio later meets Waffle and Tune, to which Match revolts, due to past experiences with recommended characters like Lego Brick. Ice Cube thinks they are nice, but Match sarcastically comparing how nice Lego Brick was.

Waffle and Book ask each other's group who they are. Waffle says that Lego Brick is a nice guy once you get to know him, but Book and Match still reject. Waffle introduces Tune but is cut off by Match's impatience. Waffle directs the three to Evil Leafy's mouth eastward, so they leave the recommended characters to continue the quest.

As Book, Match, and Ice Cube exit the house, Waffle and Book exchange goodbyes. Waffle says they are welcome back at any time. Book asks Ice Cube if the sky looks redder to her, but Ice Cube disagrees. Farther away from the house, Match questions why Waffle is outside. Waffle replies that they went on a walk to get some fresh air.

In level 53, the three are faced with an uncrossable wall. A message by Cary Huang appears behind the wall:

"Hi people. I've been really busy lately, so I've only been able to create three levels. :(
More levels coming soon. I will upload them as soon as I create them, so some could be out tomorrow, or in a week. I'm really sorry!!! I hope we can all understand."

In the BFDIA 5c announcement, jacknjellify spoils the ending with simply "FreeSmart escapes Evil Leafy".

• This suggests he updated the game that day, which would make June 5, 2013 the date of the last known update to BFDIA 5b, months after the last levels were added.
