You can see how many blocks are going to fall in VS Mode,
because before they do, you'll see coins floating at the
top of your screen, one for each block, and a different
color representing the three sizes (yellow, blue, and
orange, in ascending order).
The higher the level, the faster the blocks fall, just like
Either player can pause the game, but the player that paused
it must be the one to unpause it.
The game actually says how many hits a chain is, like in
fighting games (how cute).
