First 3 missions done.
The 3rd mission could have been done faster if I just went straight to the exit gate once it was open. But what fun is that? I've decided to destroy the rest of the ships. They stop spawning eventually.
Like always, this is not serious. The rerecord count is low because I used rewind which is highly recommended for games like this. I got the results I wanted. No missed shots and straight to the next enemy. The 3rd mission could be optimized further though.
