The little ship has learned to fly

Four days. I thought it was three. In short, the little ship seemed to fly, but not accurately. Sometimes it braked too early, sometimes too late. About 30 hours of work. I spent roughly three days looking for the error and found it. Fortunately, I also made other useful improvements along the way: a trajectory-calculation formula that accounts for starting speed, a new in-game timer mechanism, and waypoints. The little ship has learned to fly. I still need to finish switching trajectories to a different target; aiming for a moon or planet; complex trajectories through waypoints; automatic calculation of waypoints to go around dangerous areas. After that I'll connect the ship's resource-accounting system (one is ready in the previous project), planetary bases, jumps to another system, the rise in X-ray radiation at 0.2–0.5 c and the resulting damage, entry into a bubble in a rudimentary form, and interception of another ship's trajectory. Do you think I'll manage it before New Year? ))
