Lock the block

Simple reaction development puzzle game. Suitable to pass the time.

In this game you need to make voids for the falling figures. Moreover, over time, the polimino will become larger and more complex.
From the blocks below you must cut out an exact copy of the falling shape (you cannot just clear the entire screen, since you can remove exactly as many blocks as there are in the falling figure)

Controls:
* To remove the unit, you need to touch it.
* To restore a deleted block, you need to touch the place where it was before the deletion.
* To pause the game, you must click on the upper half of the screen.
