I think landing On Eve needs to be less difficult, oh, I don't want to talk about this (the last time I landed Eve, I blew up the ship countless times, and finally used debug to get past it)! Lower his atmospheric heat, and reduce his gravity, and let the little green man's single-man jetpack into orbit every time he takes off into orbit.
Also, by replacing JooI's forced detonator layer, we can increase Jool's atmosphere and replace the forced detonator layer with a land surface (similar to Jupiter's core, but very hot and stressful). It would be nice to add a little more terrain to the planet.
In addition, add more point aircraft parts, the current version of KSP parts are not enough for me to persecute the little green man (don't look at this sentence, cross it out!) Oh, and it should be the aircraft's components, hoping to add the upper crank engine and the Orion projectile engine.
Furthermore, with more planets and moons, we want to see more, novel planets, and can we add more galaxies? A Kerbol system alone seems a little out of the right. Time accelerates to increase the number of points, I went to Eello once, drove to the maximum also have to wait five minutes ten minutes. Add more real-world rocket parts and make the physics engine more realistic.
