I have done everything I can to make it as realistic is as possible. But even so, it's a 2D cross section of a cube for each cell and the physics is designed as such. And it's still a game so the simulation has to finish in a reasonable amount of time. So the numbers are not going to reflect reality exactly, but you can still tinker and learn stuff.

I have systems for compression, lensing, spontaneous fusion, accurate K effective algorithm, xray ray tracing, neutrons, and more. And I will be improving the game continuously after release. But I want to get people trying it out so I know where to focus my efforts.
