Tasked with bringing life to a barren world can you intelligently design a balanced ecosystem? It is up to you to create species of plants, herbivores and carnivores but ultimately how much control do you really have in an ever evolving ecosystem?

Intelligent Design is a simulation sandbox god game with fully simulated genetics and evolution. You control a futuristic drone from an unremarkable cubicle in an unremarkable office building. Send requests for new species and buildings to help develop an ecosystem on the landscape in front of you. At the same time as creating the ecosystem you need to study it. Build research stations to generate science and unlock the secrets of the genetic code.

Intelligent Design was awarded best free game on itch by Game Kiwi.


  • Fully modeled genetics which govern creature behavior
  • Genetic crossover through breeding
  • Genetic mutation caused by radiation
  • A climate model which tests the robustness of your plants
  • Invest in genetics research to unlock new abilities
  • Online leaderboards

There is no auto-save in this version, manually save and load with the system menu.

Despite simplistic graphics the underling model is quite intensive, a mid range gaming PC is recommended.


Alpha 13 introduced music into Intelligent Design. The single track was created for the game by MIDIEvil Studios. Raising enough money through sales will allow me to work with MIDIEvil to expand the soundtrack.
