I really liked the soundtracks in the game.It's also nice that you can play with a friend.

What can I add!
Ability to colonize other planets.Let's say that when the colonization of the planet is 100% complete, you are sent a rocket with which you are sent to another planet.To make the gameplay different, you can add that there will be dangerous areas on another planet, such as caves with gas, toxic ponds.Asteroids were larger and could destroy or damage structures such as biodomes.You can add a hunger bar and a health bar separately.For variety, you can add the ability to create drinks, juice, tea from plants, sparkling water.If you are playing with a friend, then the opportunity to make or find some kind of game, such as checkers, chess or a game of tic-tac-toe.Different planets may have different gravity, some have more, some have less, this will affect the height and length of the jumps.It might also be worth modifying the jetpack a bit, for example so that it can be flown as long as it has fuel. The fuel may be air; when the air runs out, you can refill it at the base or replace the air tanks if you are on a hike.Also, if you're playing with a friend, you can make a body beacon to make it easier to find your friend if you get lost.

Bug!
1)Having a jetpack, if you press f4 quickly and often, you can endlessly rise to the top.
2)playing with a friend you can climb on a rocket and your friend will launch it, you will fly to the top with the rocket but in the end you will fall
Personally, I rate the game 10/10.
Good luck with your development
