Impressive !
The overall aestetic of the game is super cool and those scanlines to give it a retro render are just a killer detail ^^ i also like the dynamic music changing between in mission and just chilling to get back to base, gameplay wise the controls feel very solid, i like that you not just did asteroids type controls but added lateral thrusters as well for adjustments, the landing mechanics are also pretty neat.
Don't know what more i could say really, it's a good game :)
