Considering this is an entry for a jam done in 3 weeks, that's simply amazing. Puzzles are well planned (chapeau!), the difficulty scales smoothly (the last two levels were a bit frustrating, but in a positive way) and the author hasn't fallen into the trap of turning it into a rage game just to make it more difficult close to the end. It kept me there playing, I wanted to see the end: that's not something you take for granted in so little development time.
The music: so simple, yet so immersive. Those static noises added alongside the bgm are the cherry on top. I'm literally writing this review with the main menu music still playing, it's relaxing and it perfectly transmits the idea of being lost in space, floating around. Which is everything you do in the game, so it's coherent.
Graphics: nodes are pure white, but I really don't care. Their candor fits with the theme, where the shapes resembling snowflakes gently scattered through the tiny part of space being your friend help creating a light atmosphere. Also, it creates a terrifying constrast with the emptiness of what's around you, portraying a liminal space that scares you, yet makes you feel somehow fine - you can still reset, can't you?
White particles suggesting you where you're gonna end are also a nice touch.
Last but not least, the author has curated the main menu, displaying a great economics of assets (music and background are the same assets you encounter in game).
I genuinely don't have any critique: highly suggested, congratulations to the author
