+Tips and Tricks
+---------------
+* By default the script will delete all objects starting with `Spaceship` before generating a new spaceship. To disable this feature, remove or comment out the call to `reset_scene()` around line 735 in the main function.
+* You can provide a seed to the `generate_spaceship()` function to always generate the same spaceship. For example, `generate_spaceship('michael')`.
+* The `generate_spaceship()` function takes many more parameters that affect the generation process. Try playing with them!
