The game was just updated with small content update:

• New type of planets to fight on
• Small nerf of the battle ship- now shock strike doesn't damage enemies, and both shock strike and photon strike require a little more energy
• Fixed bug with battle events in caves
• Fixed bug with cyborg boss tentacles remaining after the fight
• Fixed a couple of other small bugs

Additionally, I've finished a couple of story missions for the a campaign, but I've decided to hold up on releasing them yet, because I want to finish few more mission and release them all in a bigger content patch, for a better story experience.

A couple of people asked for patrollling enemies. I was thinking about implementing this feature myself, but now this will be more of a priority, so expect this added soon! Another update will be additional mission objective types
