Visuals
1 ... (main menu): this looks very good:
1.1 . maybe animating main menu BG would improve thing overall
2 ... aesthetics fits together
3 ... feels little static if user do no input
4 ... I do not like name of the planet at center of it -> move it somewhere else
5 ... add particle effect when taking down trees/ obtaining minerals
6 ... increase animation of chopping/obtaining resources:
6.1 . not it feels like fast paced gameplay loop
Design
1 ... unique +1
2 ... I do not like planets stacked together (give more space to bg cosmos) -> maybe animated bg to some extend with stars, cosmos, blackhole, alien ship
2.1 . you have spaceship to travel
3 ... different planet sites
Controls
1 ... if you skip
Sound
1 ... chill & changes some times -> I like this
2 ... add sound effect for player interactions

PS: Very unique idea, I think game require some tuning.
Goodluck on GameJam :)
