In the beginning, I forgot to start shooting. And then I decided to check what would happen if I didn't shoot at all but just flew peacefully.
First, I caught a relaxing vibe with music and art in the background. Then I noticed that some enemies explode by themselves at the top of the screen. As a result, I actually went through the game completely in such a pacifist way.
I also noticed that if you die too often, you may well have a negative number of lives. Moreover, if you do not move the mouse from the place of your death when you click "ready" on the screen, you will automatically die from the same bullet over and over and over again. So, as part of the second playthrough, I finished the game with minus 100 lives.
Anyway, the game gave me some fun, and that's the main thing)
I would also recommend making more understandable and gentle areas with damage in the future. Sometimes I saw that the bullet did not touch the ship, but I still took damage
