Not advertising, I don't have web or host and I'm just working on algorithms and if someone likes the idea also share codes.
OK, I was clarifying what this was for myself as well. I think the game looks pretty cool. On the magnitude scale vs. sun brightnesses, magnitude is a more well known scale, and most objects are going to be a few orders of magnitude dimmer than the sun, so you would get brightness measurements like 0.012543 and 0.02342. One is brighter than the other, but takes a little more thought to figure out how much brighter. That's all the help I can give, good luck on your project and I look forward to seeing more about.
