demolish the building Safely

Here is a challenge for you.

There are various types of blocks that disappear once you tapped.
You will be successful if you can erase the blocks in balance and remove all the blocks from the screen.

Blocks are unstable just because they are stacked, so please erase them based on what the top is like.

Since not only the tap but also the blocks that have fallen on the ground where the left and right colors are dark will be erased,
please try to break as many blocks as possible with as few steps as possible.

But dont forget this.
"Dont let the bricks touch the house."

Please enjoy this game!
