I'm actually very familiar with Star Control; most of the current and upcoming module types are taken directly from it.
Major challenge with the movement is, that although the game may resemble Star Control, its physics work more like in Elite (in 2D, though). Simulation is based on rigidbody physics, forces and masses, that (with modular ships) practically preclude the traditional arcade-movement. As everything floats in a vacuum, only small adjustments are encouraged. Most test players prefer tapping WASD-keys instead of pressing them. If you hold button for too long, you'll definitely overshoot the target.
Your feedback is appreciated and taken into consideration. Main focus of 0.4.3 will be in movement and controls. I'm planning a more accessible control method, which automatically directs the ship where the user presses (no need to worry, which way is forward). Let's home it helps.
