Space Harvest

Guide a growing civilization of bunnies for the voracious space cats who will arrive in 10,000 years … to harvest. Are the bunnies doomed to be prey to the space cats? Or will they find some way to escape their destiny? Their fate lies in your hands.

There are 4 evolutions of bunnies:

• Normal bunnies – need you to harvest carrots for them. If there is a sufficient surplus, the bunnies will breed like … well, you know.
• Smarter bunnies – can use tools, which make them more productive. You will still need to harvest carrots and ore from the mines for them.
• Autonomous bunnies – can harvest carrots and make tools for themselves. But you control the proportion of bunnies that work on carrots and mining.
• Sentient bunnies – can perform research. Researching can lead to a new civilization level, which boosts productivity and improves the productivity of all future tools.

Notes:

• The graphs are all log graphs, which means that constant linear increases look like they plateau.
• Mining and research at higher levels requires more and more bunnies.

Also, a hint for the end:

• One way to get to the highest civilization level is to set research to about 10% (and equal levels of carrots and mining) and then leaving it there until you mine one big mega tool. After that, you’ll see a population explosion and you won’t need any more tools.
