There was a lot of great stuff to your game! The presentation is wonderful, I think the effects are really well executed - it's really pretty to have the smaller bodies orbiting around you, and you have the perfect amount of bloom and screens shake.
If you continue to work on this, I think two things would be really nice to add: First some sort of depth queues would be helpful - at smaller sizes it could sometimes be hard to understand depth (space navigation is weird!) The second would be maybe having you move a bit faster at the early stages. Movement is perfect when you're big, but it was a bit slow when you're small and have to traverse a bigger distance.
Really loved your game - it's a very well put together package that just oozes good, chill vibes. Congrats on submitting!
