The mod will add a time machine.
You will be able to create a special unit, the Time Machine. Clicking on this block, you will have a special menu "Menu Time", where you have to choose the time (so far, only the Future and the Past, then he added another)
In the next update:
Added Special Tablet Computer, it will be like the Books instructions. Add new era. New mobs. Weapons and tools. Not a bad idea to add Bosses and Structures.
