Before you get ahead of yourself with 'pivoting' Nebula into a gamified social network dating app, let me just say that I like Nebula pretty much as it is, in large part due to its simplicity.

I like the narrow scope of Nebula, and would happily pay for the app to remove the ads, once you've ironed out some of the rough edges (you really need to remove the flashing indicators in the tutorial).

Naturally, if you want to transform the app into something else in the future, that's entirely your choice, and I will simply have to move on to something else that doesn't try to cram social networks down my throat.

Also, why care if a user wants to abuse the app to get more constellations? They are only ruining it for themselves, and adding rules and checks will only complicate your code.
