I love the aesthetics of this entry! I couldn't get to the Moon; only reached the exosphere. But the music, sounds and little robotic "ENTERING THE STRATOSPHERE", colours and mixture of styles are all great.
The game has the right amount of challenge, though sometimes it's hard to perceive where the debris is depth-wise. If there was something to work on, I'd focus on that (and also making the intro skippable, haha).
I was pleasantly surprised by this entry. I would really like to make stuff like this stylistically.
PS: The batteries' collision box is too small!!
