Hey!
In this version stars will eventually run out. There are 2000 and no more are added.
The plan was to start the game with a black screen, fade in a few stars based on the activity of new posts on the steem blockchain. Then the game would keep adding more stars based on posts and skill of player to increase difficulty. The posts/reputation of poster would be used to decide properties for the stars, power ups and such. Something like that!
