Overall, the theme here fits very well, and the idea has a fair amount of uniqueness to it. I really liked how you rotated around the planet, that was a very good detail and added well to the space element.
The gameplay is overall decent for a 7 day game jam and maybe I was confused at first, but a tutorial wasn't needed here since it's a very simple game.
The sun looks pretty good for the style, but the planet feels a bit lacklustre, I could tell you used a equirectangular noise texture seeing the stretching at the poles, and I did notice seams on the texture as well.
The sound is quite lacking in this game, apart from picking up the flowers.
Overall, for the 7 days, it's a good game made in the time constraint and it fits well with the theme, I may be judging a bit harsher than most others here, especially with art since that's something I do a lot, however.
