Idea itself is fun. I think you should try and expand on this one, it can become nice experience in gradually improving what you have already, also the game can become quite more fun.
I kinda can already imagine a minigame or two for each of the activities you have in your gameplay, and if done it will bring this game to a whole new level, and more content can help as well, of cource)
My main complaint for now is the amount of repetitiveness you need to go through to get a money for a key.
Left hand definitely feels a little too busy - for exmple, would be nice to bind interaction action to LMB or space instead of E.
Also seems logical to punish the player for not returning home in time to sleep? By dropping some items, for example - this change will probably require to add some to the duration of the day.
Good job with the idea as a whole, keep on!
