What constitutes a "move"?  Some levels require the OCD to be completed within X moves or less.  Does moving goo balls around count as a move (but not building anything with them)?  What about removing a green goo ball from a structure (is that a "move"?) etc.
Thanks for any help

Just moving a goo ball doesn't cost a move. Any sort of attachment or detachment will count as a move. Also, I'm pretty sure using a time bug won't remove any moves, so they're bad for ocds that need you to use a certain number of moves. I don't think the actual clicking of the time bug costs a move. I think that covers all the scenarios.

what about blocks?  What constitutes a move  on the levels with the square and rectangular building blocks?  Thank you for any reply.

picking up and putting down = 1 move.

Also 'tricks' like letting it go mid air and catching it at the end is a move.

Basically, any time you click on a block, and release the mouse.
