This is how Loopy does it and Bob too, Give it a go go.
Spoiler-
First, the the Left generator fill all the way right. While it's doing that, push the left cube down one and the right cube over 1 down 1.
After the last boulder goes past to fill in the water, move the right cube down 1 to stop the next boulder. Push boulder down.
After the next boulder comes to rest, push the left cube down one. Then in one fluid motion, push the boulder down and the cube left to bust the new boulder and block the generator.
Grab the coin off the conveyor button and the coin to the right of it.
Move the right cube past the generator and ride the conveyor to get around it.
After the last boulder fills in the water going down the middle, block it with the cube.
Go all the way to the right and carefully grab the coin blocking the down path of the generator. After the 4th one releases, grab the coin from the left side of the generator and step out of the way.
The red boulder goes in the water. Push the green one in, too and the other green one bounces back and explodes the keg.
Go through false wall to conveyor.
Move the plasma cube left and then down to the conveyor button.
There are two jump sequences to get the next batch of coins. They can be done in any order. I'll do the short jump first: After the tramping boulder goes down, walk and stand next to the tramp. As it jumps over you, jump DD and quick step Left. Get the coin by the cube and the other one that's on the ice.
Carefully tramp UU and step L to avoid the boulder and leave the area.
The other jump sequence: After the tramping boulder goes down, walk and stand next to the tramp. As it jumps over you, jump DLLLLU to land way at the top and get the coins in the corner.
Walk off the ice and start that boulder in motion. Exit area via false wall again.
Walk down the middle boulder path.
Walk into the right room and in a quick motion push the yellow Right and the blue down and hold still so you don't get bouldered.
Go up and hit the teal button.
Walk on over to the left room, but careful of the yellow gate. get the last two coins very carefully because the blue boulder will roll as soon as the exit gate is down.
With that boulder on the blue timer, get all the bonus coins and exit.
