A classic redone with style and clever twists!
I love the alternative modes and how one needs to EARN the power-up via skillful play.
My once suggestion is jut that they might want to consider some sort of progressive scoring so that each successfully created line in a row gets you a score multiplier (so if just doing lines of 5 balls it would be 5, and then 5x2, and 5x3, and then once a move was made that didnt clear a line, the next line is back to x1).
