I'm so mad - I got wayyyy too carried away boosting around that I crashed after a measly 7 planets saved!
In all seriousness - this is one of my favourite entries so far - potentially my favourite. The audio, polish, art, movement - aaah, it's all perfect. There is so much I want to pick your brains about here, but in the interest of keeping it brief, I'll only ask 1 question! The subtle pixel differences in the spinning planets/moving spaceship. Were they done using shaders? I find it super endearing and it really fits the art style well!
The only nit-picky thing I found a bit unengaging was that you could just stay at a planet to max out on that resource. It means the winning strat is to just permanently hold E as you fly around.
Overall, really glad I downloaded this. Congratulations, hope this steals the show!
