If you haven’t already, I think the most helpful thing is to go through the next couple areas.
Finally!!! I was able to solve it!!!
I already had all levels solved until Variety where now I have 9/15 solved, but I couldn't see how to do Idea until I thought about doing that.
It wasn't easy at all, this game has truly astonishing puzzles.
I also already solved all levels in Bloom, only 2 levels left in Ceiling, and I reached to Advanced where I haven't been able to solve any level yet.
