Loved the graphics as always. Also loved how you've balanced the game. It never felt like my deaths were my fault.
Thought for a while that Mercury was a lie so I decided to play for as much time as I assumed it took to reach Mercury from the Sun. Sure enough, I got to Venus at around 495. Good job on that touch! :)
The 99% at light speed is kinda betrayed by how the meteors come in faster implying that you're moving faster with time. I get that there needed to be some progression but it does kinda stand out at this otherwise well developed submission. :)
