More realism! An Hard mode?

Congratulation guys! It was a long time that I expected to come out, and I already played the 2d version both on PC and on Android!
It would be nice if during the maneuvers (especially in the atmosphere) make the whole thing more realistic, the rocket changing direction so quickly would break in two.
How magnificent it would be to have a difficult mode available with the real solar system.
I had already changed the 2d version with the solar system and it was really fun.
Arrival from KSP (also hypermodded), one of the most beautiful things is the realism that give some mods. If you could do it while still maintaining the "simplicity" of everything as you already do it, would be great.
It's just an suggestion...
In any case, wonderful work, I'm thrilled to finally be able to play!
