Weird. For some reason I'm experiencing many more problems with this version. Spoiler: My experiences In fact I can't finish this version because no matter how I play it (i.e. where I tap), B keeps falling into the space created beside the ball after partially pushing away the movable pillar closest to the ball (the one with the motor on top). I tried just getting B to push one at a time or both in one sequence - same effect. I also had B end up on the stone block on the corner beyond the second lift and once he decided that he'd rather scramble around the first movable pillar (motor on the bottom) than push it.
@nGord Spoiler That shouldn't happen if you go straight first (with the ground slider at its default position) and fully push the whole thing forward, then move the slider and let B walk in a C-shaped path to knock the small obstacle away. Let me know if you still cannot clear the path to the goal.
Pure use of 2 techniques done perfectly, I have a lot to say about this one but I'll just let it be, this goes into my top favorites :3
