I think some of Steph's scores may verge close to being records. The only times I see higher scores involve people that play the game on an easier setting - a setting so simplistic I do well on it.
I want her to have some kind of competition to spur her forwards, and have no idea where to turn. Twin Galaxies is the only place I know of for records, but someone has a score put up that is "perfect" which I'd imagine came from playing on the easier setting. Beyond that, she's got double the score of anyone else on there. And that's one of the homes of high scores in video games.
Not expecting any answers, but whatever. May as well throw it out there, maybe even get someone on a nostalgic Columns trip.
