So, i think allot of people have been suggesting this already, but i think we should have cosmic radiation to make the game have a real feel too it and to make it more fun and challenging, basically like a random timer which when hits 0, a supernova takes place, and you have to avoid the alpha, beta, and gamma particles heading in you general direction, if hit with the radiation you lose communications with the earth temporarily, and it weakens the infrastructure of the space craft, in this case i would also recommend a update where you can buy and assign different space suits the crew, with different properties such as radiation resistance, RCS fuel and e.t.c
