How do you know when the difficulty curve of a game is nearly perfect?

When you unlock the high-score achievement within ten minutes of unlocking the cumulative-number achievements.

Adamvision really knows his way around single-button games, and this is one of his better ones. I 100%'d it in about an hour, but this is really a game you should play for a few minutes at a time when you aren't able to sink your teeth into anything more substantial.
