After playing it for a few hours I must firstly say that I do enjoy this game, but there are some things that I believe will improve on it.
The money system is all based on over time gain/cost. Housing has an Initial Cost but still cost money over time. Add a shop where you could buy items with money. Like a vacuum cleaner that deceases you chore time or kitchen utensils that improve your foodquality by a percentage. Right now I am saving up a lot of money, can buy a better house, but not afford the rent. Basically, one time purchases to use your over time stacked up money.
Add a bit op personal life to it. Right now it is Groundhog Career not Life. Might be able to add an event that gives you a friend, that improves your happiness. Add an tab with stats of your friends, if you neglect them they will go down, spent time on them and they increase. Or the possibility to buy a hamster/bunny/cat/dog/elephant, it wil cost you chore time, but increase your happieness by a percentage.
