it's sort of like those "color flipper" games, where hitting one color affects two others, so you try to "balance" them... more or less.. um, right? i really wanted to figure it out and beat it, but couldn't quite, the brief presentation of the rules at the beginning didn't sink in enough, and still sometimes seemed that it worked "backwards"? (not that it really is, just that the confused understanding of the rules makes it appear so) it might also help if there were some "local" (near the clicked dot) animated feedback if you actually click the dot in time. sometimes it's very split-second and you miss noticing the bars. also occassionally dots get stuck near top of screen when starting a new game.
