Let's break the block!!
The color of the block reverses when the block is traced.
The block breaks when the square is made in the block of the same color.
When the block empties even by one line somewhere, the game is clear.
There are three kinds of modes, that is, S, M, and L that the amount in the block is different.
It is possible to play slowly by my pace because there is no cornered thing like the time restriction etc.
