Thanks! I was originally thinking about some kind of hybrid between an RTS and city-building game. There's code for different kinds of ships (both enemy and friendly), more sophisticated structures, multi-screen expansion, and of course saving (which is not completely implemented).
On the city-building side, I used the AI graph toolset to manage how structures are linked together, so I could implement some kind of agent-based simulation. The population numbers are small enough that managing the colony can be done on a person-by-person basis.
Once I realized I wouldn't have the time to do all that, I scaled it back to a simpler idle game. I think it works well enough that way for the jam, but I wish I had more variations of buildings to unlock so there's more of a sense of progression.
