It's vanilla with plans of a number of updates if the launch is successful.
It's like an endless progression game (game over when your reputation reaches 0).
Currently it has three main characters that you can develop as you progress a run.
There are also a lot of unlockable events in the game, and can be viewed in Memories, together with unlocked scenes from the main characters.
Lastly, there are upgrades and unlockable structures that can help i your next run.
Hope I answer your question correctly.
