Thanks for the feedback, I wanted to have some enemy AI but ran out of time.
At the end I had to decide between having more than one enemy ship or having A enemy ship that could move and decided to go with quantity over quality 😅
Thanks for the note about the number of ships, the are randomly spawned as you kill one so there is technically an infinite number of ships but I do think the spawners might be too far spread out for 5 minutes, originally the round time was 15 but I felt there just wasn't enough to do to justify that long.
