hey robbi I had an idea for the mod. Well it was that when a ship is hit oxygen gets sucked out so you have to add a door type thing that seal off sections. And if your ship isn't air tight oxygen can seep out slowly causing your crew to suffocate. Also with` that there should be a pulling force when the oxygen is released into space. ex: hole blown in ship you get sucked to words hole(if on same level(less pull higher up levels are)). You can be stopped by a block, but you can also be picked over the block and keep going.
