Sobics School, an original bricks matching puzzler

Objective of this original and funny puzzler is to arrange groups of 4 or more same colored bricks to remove them.
To achieve this, move the "Teletubby" style doll with the mouse under a column of bricks. If you click with the mouse the doll catches the bottom brick of the column. Now move the doll under another column where you want to place the brick and click the mouse again. Wall bricks cannot be moved and with dynamite bricks you can remove a hole column.
