As much as I love this game, I just realized that there is a major problem with the in-game physics. If I'm in deep-space, then I'm in a vacuum. If I'm in vacuum, then all I need fuel for is to attain a speed, not to maintain it. If I'm at a constant speed, my fuel level should hold steady. Likewise, if I'm constantly burning fuel, my speed should be constantly increasing...

fuel is an option you can turn off, but the updates are on the steam version.
