This week I worked on these:

1. Added a payment deadline:
   1. When you move your robot on the planet map, in-game time advances and days pass, if you reach the deadline you have to pay money for business maintenance and salaries.
   2. If you run out of money you go bankrupt and you loose the game.
   3. Hover your mouse over the deadline text at the upper bar to see a summary of your expenses.
2. When you explore, if your explorer runs out of oxygen he starts loosing health until he dies.
   1. In future updates: You'll need to hire a new explorer to be able to explore again (I don't want to disable exploration since there is no way to hire employees right now).
3. Creatures can attack the explorer and kill him.
