Cube (of Surprise)

oh yeah ..it is

Spoiler: Hint ...

B can only move in the constructed game arena ( buggy ), that's what makes it possible to move B only when he is beneath the cube

Spoiler: Example

You can slide the half-box half-way (making B's path beneath it n allowing visibility of it)

The GamePlay Is As Follows...

Spoiler

Spoiler: Think Fast

Make B fall into the half box while its opening (for only once)

Spoiler: Positioning

next part requires R n B's entry to the other half but different paths

Spoiler: Finale

I don't think so, after this any explanation is needed

Spoiler: Well...

...or you just open the cube and pull that long free draggable on the win...not so much fun...

I had passed a very logical way Congratulations liked
