@villeloso When the camera zooms in you can see less of the playing area of the game. My issue was that it zooms quite far in when you get close to the black hole which shuts out your view of the wider area. This means you can't see where might be the best direction to fire yourself and if there are imminent hazards that you need to avoid.
Also, the amount of camera movement seems excessive as it is constantly lurching one way then the other. It seems unnecessary as, while you need to keep track of your craft, everything in the game centres around the black hole and you need to know where your are in relation to it at all times. You could have had the game static, with no camera movement, and the game would play fine as you never need to see your ship up close.
However, I can see that camera movement makes the game more dynamic and, therefore, exciting. So, it might work to have the camera zoom in less and to use lazy following where the camera doesn't track the ship exactly and doesn't make any abrupt movements. There would be a slight lag to the camera with some easing into changes of direction. Again, this was just my feeling playing the game and I am not an authority. So, I'm not saying there is anything wrong with your game just the changes I would make if it were me. I do like the game a lot.
With that in mind, here are a few additional thoughts on refining the game. How about starting off with fewer objects (especially the red ones) so that the player can ease in to the mechanics of the game and then the difficult ramps up as the number of objects increases over time. Furthermore, it might be interesting to how most new objects start with a velocity tangential to the black hole so that they are more likely to orbit (unstably) rather than flying straight down the throat of the black hole. This would allow for a more tactical approach as the player could hop from orbit to orbit more easily. The chaos would come from the interaction between objects and the, now rarer, kamikaze objects heading straight for the black hole.
