My honest feedback: The audio fits the game well and I think the kind of game you chose to create fits the theme of the game jam well. But when there's light, there's also shadow.
I can't really understand what the purpose of the ship is, it seems to me like it is just following the anchor that can be controlled with the direction keys. I had to read the comments to find out what the numbers on the asteroids actually mean, at first I thought they were the amount of points I'd get for collection. Why is the ship so hard to control in contrast to the anchor?
But I'm glad the ship shoots automatically.
