Thanks for the play! Limitation is not very obvious but fair point, it is just the time remaining and max decisions you could take.
For the gameplay, the original scope is actually way bigger, so it was cut to a sort of simulation type game. Basically you are a vigilante trying to stop crime, and you can choose to spend time to prep decisions that would interact with the game world. TLDR: kinda like batman arkham without combat and pure sims.
