This isn't really my kind of game, so I didn't really get into it. However, it does seem like an interesting take on the concept. I certainly found all the complex interactions to be interesting, but too much for me to personally keep track of.
On the topic of accessibility, I found the use of color to be problematic. A number of the planet effects refer to the color of the planet, but I had a difficult time being sure what planets counted as certain colors. Being colorblind, even when the number of specified colors is low like this is, I do still find myself second-guessing things (eg. "is this planet blue, and therefore affected, or is it a purple planet or something?"). In general, I would have liked more indication of how adding each planet would affect the result (eg, and indicator when hovering over a planet that shows that planet A changes by +5, but planet B changes by -3).
