Wall mode all apples small map?
Proof of concept: https://scratch.mit.edu/projects/458516251/ If it is possible for the walls to be in this configuration, you could probably finish the game. It would be easier to manipulate the position of the walls in multi mode since you could leave apples in places where you don't want any walls.
It's still very grindy even in multi wall mode small to get lucky enough for an all apples to be possible, but we do have a TAS up for it:
