Interesting concept :)
I would focus on UI or tutorial. Because a lot of things happening at the same time.
Some points:
- I am not sure what exactly "send home" does, didn't notice an effect
- The most effective I noticed is "practice scripts", when level is increased, receiving calls gives some money :)
- Also not sure if "kittens with phone number " did a lot, it was kinda cheap, but I was gaining money in the end.
- I didn't noticed "police attention", maybe some SFX and UI effect on that stat would be nice :)
