Woah this game is incredibly cool. This is one of the more original games i've seen in a very long time. I really like how you give the number of moves and the time taken as a stat. This map is an incredibly showcase of what one can do with the new UI manipulation. I played this with with 5 other friends and we all had a blast.
I have some minor suggestions.
First I think it would be nice if the host could end the puzzles, without everyone voting. Sometimes as we waited on a player to finish, it was annoying to get everyone to click "end puzzle".
Second, the lines that separate the puzzle might be a little too wide when there are many puzzle pieces. It would cut off part of the picture.
Third, I wish there was some way to prevent getting the same picture over and over.
Overall, this is a wonderful game and I give it 5/5
