Here's my rating:
The gameplay worked well, and it was fun for a little while, but it got old very quickly. I actually ended up killing myself because I had seen all the game had to offer in the first 20 seconds. It's also really easy, and most crucially, it doesn't have a highscore system (or scoring for that matter). My rating: 2.5 (rounded up to 3) stars.
It fit the theme. What more do I say? My rating: 5 stars.
The art is really well done, especially the ship. However, the stars that you're dodging look rather ugly, along with the particles that go off when you die, and because they look significantly different from the ship and background, it looks like the art was downloaded from the internet, not hand-made for the game. I don't doubt that the maker of this game made the art in the jam; rather, I am making a point about how it is implemented. My rating: 4 stars.
There's literally no audio. I don't blame you: it's hard to make audio in a jam. My rating: 1 star.
Overall, the concept and art were both well done and thought out, but the poor gameplay execution (and lack of audio) really put down the rest of the game. My rating: 2.5 (rounded to 3) stars.
