What happened here ^^ Finally I beat the boss, but I'm not sure what happened during the game, Maybe its a bug, but my spaceship disappeared and the screen gets blue:
Overall, nice idea. Navigating in space is very challenging, but perhaps that's intentional. The sound effects fit really well, and the art style matches quite nicely too. Despite their simplicity, the boss attacks feel powerful.
Maybe a small indicator of where the boss currently is would help, especially if the shotgun knocks me back to the edge of the universe again. lol
