I love the original idea for the game and how the space looks, with lighting and beautiful starry sky.
I think gameplay suffers from your failure being sudden. You don't see the asteroid that's going to kill you. Maybe it would be more fun if it was easier to see all the asteroids in the sky but actually deflecting them would be more challenging and requiredcareful resource management.
It's very easy to undestand how to play, the controls are intuitive and I didn't have any technical issues.
Great job! Good luck with your future projects!
