Hey, from the author. I dont think it is impossible (it is hard though). Wiping a line is not necessary you can slide left or rigt to collapse them.

But, i am also increasing the tendency of the block to freeze stronger as it moves down (i.e. with its every movement), so that sliding left or right doesnt become that easy.

There were few bugs with that, which i fixed. Does it still sound unreasonable.
