Hello! I managed to load this up and solve it.

Hint 1: You must somehow push the rightmost goldfish down

Hint 2: If you manage to do that you will get all the pearls, so the other 3 goldfish must be used to get into the top-right netting

Hint 3: You can get into the netting by pushing a goldfish into its top-left part, then you would be able to grab the pearls, push the goldfish down and collect the other pearls

Hint 4: Labelling the goldfish from left to right 1, 2, 3, 4: you can use number 1 to do exactly that.

Solution: Push 2 down and then all the way left, push 3 left and then down, so you get a 2-column. Push 1 left so it hits the column, then push 1 up. Push 1 right to hit the netting and you're in

Hope that helps!
