burnt vapor
I was attempting to beat this challenge when a crash occured.
My solution was to use area bubbles to duplicate and grow as much object as possible followed by using push bubbles to get them in the chamber. At this point, some object began clipping out of bounds.
After pushing all the yellow buttons and getting the first coin, I would follow up by transmuting as many object as possible into sticky goo and using rise bubbles to hit the red buttons.
At this point the game crashed.
