One oversight would be failing to account for those with visual impairments since the way the text is currently is giving me real eye strain, so as an alpha tester, I formally request that you guys please try to fix this because it prevents me from testing it properly.
One bug, which I guess is due to black holes being incomplete, whenever I try to change the mass of it, its mass and diameter resets to that of a dust particle, even if I lock either value.
Also, I'm not sure whether this is a bug or oversight, but no habitable zone for very hot stars like Rigel and Deneb?
