The game even has logo splasharts at the beginning, it looks really professional! And the music reminds me a lot of Metroid's OST, one of my childhood (and still is) favourites. I think your game is the first one I've seen with an actual options menu!
The tutorial is really good! And online highscores?! Mechanic-wise, your game is really complete! I couldn't play for long since I had to finish some stuff, but overall your game feels really polished.
What I missed is a pause button! I had to stop playing but there weren't any so, I just crashed myself against a planet (that was really fun ngl).
Maybe it needed a little bit more of variety since the game felt a bit repetitive after a while. Like being able to improve your ship's cargo or recollecting speed, but those are just pet peeves of mine. I understand that'd have been too much for a jam. The gathering resources and travelling from planet to planet reminded me of Spore's space stage. Fantastic work, good job to all the team!
