Whose House?

my feelings in succession:
:mad::mad::mad::mad::mad:

Spoiler

there is something hidden? How can I move brown piece?

and the owner should enter his home (?) ...

Still, too hidden, but tricky design nonetheless.

This might be a little late, but I've found a fun way to solve it without using R......

Let B die inside the house, and use @meko 's ball control trick to slowly make B roll by the Win (just like the final move in @richardfu_ 's "Last Mission"). It'll take you some time to get B inside and make the 90-deg turn, then you'll have to shake the draggable platform so that B's dead body would vibrate and trigger the Win.

@meko best use of the emojis I've seen yet! I finally beat it!

@sawdust You may now add two more emojis to the end: .
