Cool game! I often run out of energy. Is the current energy/fuel level anywhere to be seen? Edit: Wait, its Joystick down, wow I played a while before realizing that.
Thank you for playing and commenting! In the early game, you have to be pretty conscious of energy use, especially when you start travelling between star systems. After you find a few artifacts and/or get better at orbital mechanics, this becomes less of an issue. (Hint: let your momentum carry you and be patient)
