Valgus^2

Valgus^2 (pronounced "Valgus squared", and henceforth referred to as VSQ) is naturally the sequel to Valgus, which itself was a public domain version of Tetris. In VSQ, the seven familiar Valgus pieces as back, but they are tired of falling straight down the screen! Instead, they will come at you from all four sides of the 27x27 playing area.
