I love the look of the game. The shaders are awesome and the music is great. Obviously the black holes look awesome, but the stars also have a very nice pulsating color and look.
Gameplay-wise I think its a bit unfair in the sense that you are almost always going blindly. Even if you re going very slowly, the other starts are coming in very fast so you cant really dodge them when you view your play this closely. Otherwise the controls are fun and I enjoyed it.
Maybe a bit slower gameplay, a bigger visible are and gravitational interactions could improve the gameplay.
