Once you complete the tutorial levels, that's pretty much all this game is. Kind of infuriating game design as well, to be honest, from having to learn the schedules of every house, to having too little inventory space to actually clean out most houses in one go (meaning you have to make multiple trips) it all adds up to a cocktail of frustration instead of the actual joyful glee you should be feeling at being a thief.
Lesson learnt, I guess - crime is boring.
