To increase energy you can sleep, drink/buy coffee or drink/buy energy drink.
To make money you can go to high class apartments (between 7~9 hour) or Night club (between 5~6 hour) and work. In the future versions it will become a minigame...
In the future versions you will be able to have a carreer. With a carreer you will be able to make a lot of money. I'm thinking about add "cheat mode" in future versions. I really wanted to see how the game goes with just basic mechanics.
