Isolated House

Not a fan of hidden passages and I don't mean the water but passages that you can't see. Levels can be hard enough without any hidden.

I agree with @gmacpro
It started out nice as I could view ahead to where B can go after I drop a ball, but then I thought I would be going to the finish, but I was wrong. And I didn't see any way to the finish

@Sculron -

Spoiler

Did you see the slider just above the win to the left of the ball? It was hidden well but I couldn't see what to do with it?

Pushing the four balls was pretty straightforward but it took me more time to figure out how B could reach the win. I did not use any hidden elements, so B's final step may not be the designed solution.

Thanks for the feedback guys! I included some clues.

Clue 1: The hidden slider is placed next to a ball. Zoom it. gmacpro got it. Clue 2: Hidden slider allows B to be dropped from above.

Uuhhm,this level was a long time in my "unfinished levels"folder waiting for inspiration....And today the inspiration has not come yet jajaja ... And I've completed it just by using a ball and a trick ...I saw the hidden draggable but didn't know its purpose...a pity...Thanks for sharing @Jorz
