Thank you for playing and for the honest feedback! I’m really sorry to hear that the arrow keys didn't work for you, that’s definitely something I need to look into and fix. I also agree with your point about the UI layout; I'll definitely look into spacing them better for PC players.
Your idea about being able to move closer to the Earth for a 'last-chance' intercept is brilliant! It would add a lot more depth to the gameplay and make those near misses feel much more intense. I’ll be keeping these points in mind for my next update. Thanks for taking the time to share this!
