This is a great little puzzle game with a totally original concept! I loved it, but I just wish the instructions were shown in-game, instead of only on the store page.
IMPORTANT: Both of the middle two rows of desks count as THE SAME ROW!!!
(The game counts a girl sitting in the second row and a girl sitting in the third row as being in the same row. It's a bit counter-intuitive, I know, but I think it makes the puzzles better.)
