Bunker

Story(it's important for the completing): While Bill and Rick were still in ruins, Philip found an old bunker. Philip decided to climb on the bunker rooftop, but suddenly roof has broke under him and he fell down. Pointlessly roaming in the bunker Philip found metal button and blocked door that leads to the ground floor, but he is not tall enough so he'll need some help from Rick, because Bill is not strong enough. After some time Bill and Rick finally came. And Philip told them everything. Now they need to push the button to enter the ground floor and be safe in it, until the war ends.

Philip must open big and metal door.

Spoiler: Finishing line

Philip goes to the corner near the button it's at the top right zone of bunker, and Rick comes next,place the slider that comes from the roof near the button so Philip won't fall, and finally punch the slider and Philip will punch the button with his head. Now Bill can go to the winblock at the left.

Fantastic stuff. Loved the herding of R at the start and the need to avoid a few traps. Fell for a trap inside the bunker first attempt but herding of the two Rs went smoothly after that. Great finish.

On my 2nd attempt, as I raised the mechanism to start, it disappeared and I got a check mark as complete so something isn't working right?

I continued on and it happened 3 or 4 more times. Trying to attempt the level as intended, I went to your hints as B was able to drop one ball (I think right) and your hints don't help on how to get to the ball. For example, B jumped once and got the R ball but I can't seem to duplicate the trick again? As per the high ball, again B can't get to it. Looks like a pillar squat drop move but B will not do it?

EDIT - PS. What's the point of the metal cover at the start? Obviously it serves no purpose other than allowing me to win.

Fun level!The box suddenly disappeared. Thanks for sharing!

@gmacpro it was made for the night mode, i took this idea from @Tadashi Suzuki's level Night forest. Mechanism is needed to disappear. About balls

Spoiler

R needs to drop one of the balls, and you need to make some R herding.

I think other hints you will understand, if you know where's the button which is also written in hints.

@gmacpro I think the "explosion" effect sometimes touch the win. It also happened twice to me...

@chemi @gmacpro I had this problem, but it doesn't happen very often, and I couldn't fix this, so I left the night effect because, it's not so annoying, sorry if it happens often on other devices I'll make card without the night effect.

@Br0K3N no problem at all. Still trying to finish it...
