To escape, you will have to grow food, find resources, fend off the nasty hungry things, and still free up people to build your ship. Maybe you'll have hardly any wood. Maybe the natives are closing in. And maybe the lions are just really, really fast. Think fast, and plan carefully.
Any moment can make the difference between being free and clear, and being a tasty snack.
So sharpen your axe, and get on your running shoes. System 7 is also required.
