@GameDadGrantIt's $7, and it's great! Don't play the classics they just put on NSO, play this!
The premise is that fall speed increases until blocks appear on the stack instantaneously, and every is balanced around this. You need to be able to pre-rotate pieces before they spawn, which means there needs to be a slight delay between when they lock and when the next one spawns. Allowing for infinite spinning would defeat the purpose of high speed, so that's out, and there's a different set of rules for how you're allowed to move a piece after it touches down but before it locks.
Because the performance expectations are so high, there's no reason to treat the game like a marathon anymore; you place 999 pieces and then the game is over. Surviving until Level 999 is a massive challenge unto itself, and then you get a rank based on your performance. It's gameplay density, all killer no filler!
