Gems

Gems are a currency in the game. The player can use gems to purchase the FuelBots, Dark Matter Fuelscoop, Infinite Backpack or boosts for/during your rocket launches. They are obtainable through Island chests and spending Robux by clicking the + next to your gems.

Another way gems can be collected is by finding 250 at the bottom of the moonlings Island (altitude) Board. By clicking the moonling at the bottom of the board you will be awarded free 250 gems. This can only be done once per game. A player can also collect 250 free gems by going to the Cave of Eye planet and entering the cave bug's cave, talking to him will give you 250 free gems but this can only be done once per game.

You will also get an extra 700 gems if you were to finish The Zenith's Light Orb quest. You can keep doing this every time you rank up.

While launching you will find that there are 2 buttons that appear on your interface. These buttons are as follows: In total, you should be able to collect a total of 14,550 in Moonlings or 17,150 in The Zenith.

In total, a player can collect up to 31,600 gems.

Warning: For some reason, if you rank up in a dimension, your other dimension will NOT reset. Meaning you have absolutely no way to get the "supposedly" maximum amount of gems. The most you can make is if you finish the Moonlings dimension and only rank up on The Zenith which will get you up to a total of 18,500 gems. If you do vice versa you will end up with only 16,100 gems

How do I spend gems?
As you spawn in the world you will see a gem shop directly in front of you! By heading to the gem shop you will be able to spend your gems to get special boosts or items.

You may also spend gems on FuelBots. These can be used to collect fuel ontop of what you are already collecting or if you wish to be idle.

Or as mentioned before, you can use gems whilst your rocket is flying through the universe increasing the speed of your rocket or simply adding more fuel, just incase you couldn't make it ;).
