I've been reading that and I told myself "Maybe I should check that out".
So, under the guise of a guest, I went in there and tried it.
Since I came from Tetris Friends, the default controls were....difficult to master (it must take a lot of getting used to it).
So I changed the controls to that of TF and played a Classic game.
When I was at Lv15, I couldn't believe that I could still see the pieces falling; on TF's Marathon, at such a level, the pieces were dropped almost instantly.
And I told myself "This isn't Grand Master, this isn't Grand Master..." (I had a taste of the "invisible credits roll" on TF Survival, minus the credits)
A while earlier, I watched a video of "Blink v. Corrosive". I couldn't believe what I saw.
The level increases with EVERY Tetrimino??? Are those really TGM conditions???
But then, I've never tried the TGM series...would want to, but never could.
That was my 2 cents on BlockBox. Maybe I ought to sign in there
