Ahh, this is fun!
I found a bug with level 7 - if you just move a not'tribble next to the other one, it counts it as 0 moves and you can't pass the level. :( Took me a few goes to figure out I needed to move one halfway, so it'd count as 1 move.
Thanks for the bug report! I knew there was a problem with the move count, but didn't realise it was stopping progress. Will get that fixed asap.
