Thank you very much for playing and giving us detailed feedback. I very much agree with all of your points. When I was designing the asteroids, I didn't think about the shape and how that would affect the player's behavior. This is actually great feedback for me, thank you very much. Making the red indicator change size depending on the distance to an enemy is such a clever idea. I'm taking notes! We actually wanted to implement a sort of health bar for the collector ship (bumping asteroids around, loss of collected ressources, etc.), but didn't managed that to implement due to time constraints.
Regarding the music: yeah i have noticed that after the 48 hours mark, so we decided to not fix that.
Again thank you for taking your time playing our game and giving us insane feedback!
