As I recorded this after the rest of the course, I might have made some unintended minor changes to the enemy code, but hopefully they shouldn't affect the assignment.
When it comes to assignments, what matters to me is the part that solves the assignment. You shouldn't worry that there are some differences between your code and mine as long as the characters are working as intended.
When it comes to code, there are always multiple solutions to a given problem, sometimes many.
I'm used to working and teaching at professional level. This course being my first "beginner beginner" course, I made some unintentional changes at times, without realizing it.
Note that when you share code, you can select your code and click the </> icon in the text editor on mavenseed. It will keep the code formatted.
