This is great! Moving the ship around feels great! Stopping development before over-scoping is never easy, it is one of those lessons we all have to keep learning. If you ever get to continue working on this, I feel there is one thing that is more important than the rest of the todo list: have not only the ships, but the bullets that are shot off the screen reappear in the other side. Loving the vector-style graphics by the way! Keep it up Charles!
