I think it's interesting how, and no offence to the noobs, the regulars of the forum and those that have shown themselves to be more advanced don't mind, while it's usually the people who have just started either the forums or the game complain.
Haha. "No offense to you noobs, but you suck! Learn how to play better."
But yeah... you get used to the game's quirks and learn to compensate for them when you've been playing longer. Since originally posting this request, I've learned to anticipate the problem and be more careful about dodging blocks of pretty much all colors when I'm getting ready to paint/sort a full grid. The paranoia makes me a better player, I guess.
I'm not saying it should necessarily be made easier. Maybe the rule should be that matches always behave this way (meaning taking that extra split second to register and causing an overfill if you stack a block of a non-matching color on top too soon) regardless of how they were attained, and if you're not quick enough to avoid the overfills, then tough noogies. Easy or hard, I just think it should be consistent. The rules seem arbitrary as it is now.
I'm just saying - if I overfilled on the song, I'd be redoing it because an overfill means that the loss of points (-10% of the total score I think + the respawn time) basically means you probably won't be placing very well on the scoreboards, unless you have found a pretty empty scoreboard.
I usually cut my losses and restart the song when I overfill, but if it's at the beginning of the song, 10 percent of close to nothing is, well, close to nothing. So unless it loses me a good powerup or a row with a few whites in it that I was trying to sift down to the bottom or causes me to miss a good opportunity while respawning, I'll generally let it ride.
