I think you missed the point or maybe is it just buggy? I don't even know how I won... After a draggable movement. That was kind of surprising
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...
