Through Block Ext

It is a falling game.
When the falling blocks line up in a row, the row disappears.
When the block can no longer appear, it is finished.
There are 40 types of block patterns.
As the level increases, the types of blocks that appear will increase.
If there is a gap in the block on the screen, a semi-transparent block will appear. If there is a gap below this block, it will pass through the other blocks and enter the gap.
For operation, touch the screen.
Rotation: touch
Move: Drag
