It looks amazing! A lot of things in the way you use audio and UI really remind me of some old games I used to play when I was a child. The flying part was very cool but it was short. I was very confused about the puzzle that felt like a completely different game and it completely broke the flow of the game for me, especially since the game restarts and we have to go through all the transitions to do the flying part again. If that was my game I would lean more into the flying part, expand it with new mechanics and make it fit more the theme (show actual stars instead of big dots, drawing the actual constellations in the 3D world and maybe some space-themed obstacles like asteroids, planets, black holes instead of these rock-like structures).
Also the title and description feel very AI generated. Maybe I'm wrong but it really gives me this feeling. It's fine and it's allowed but the tone is very robotic and lacks personality. A description that might be short, flawed, simple or complex, if you write it yourself and use your own words, it will remind us that there is a human being behind the game. Everything feels more rewarding if we know there is intention behind each choice, each mechanic and each word. That's probably the thing I want to draw your attention the most, more than anything in the actual game.
