About Intelligent Design: An Evolutionary Sandbox


In a universe driven by targets, a faceless corporation employs you to create an evolving ecosystem you can never hope to control...

Intelligent Design: An Evolutionary Sandbox is a god game with fully simulated genetics and evolution. Create species of plants, herbivores and carnivores and try to control the ever evolving ecosystem. Design and create genetically modified organisms, but remember when you start tampering with genetics it is hard to undo your mistakes...

This is a game for people who don’t want to be given all the answers. A game for people who like to experiment with a simulation, at their own pace, and watch what happens.

Key Features



Fully modeled genetics and evolution

The behavior of each organism are determined by their genetics. How tall will a plant grow? How fast can an herbivore run? How often does a carnivore seek prey? These genetics are passed down generation after generation along with random mutations. Evolution is fully simulated, there are no tricks or statistical approximations. You are watching life evolve on your computer.

Science to be Done

What do all those genes actually do? How is the world score calculated? What does world efficiency even mean? Much like a real scientist you will need to investigate, analyse and work with other players to try and answer these questions. To help you along the way the game outputs data in xml files so you can really get your science on.

Genetic Engineering

Create your own genetically modified organisms, but be careful, once a genome has entered your ecosystem it may be hard to undo the damage ... and are you sure you really know what those genes do yet?

Secrets to Discover

Who is employing you to create this ecosystem? Why are they doing it? Why are you doing it? What are those targets for? The answers to these any many other questions are out there, you just need to work together and find them...

No Generative AI was used in this game. We pay humans for art and music.

(game not complete at .5 hours of gameplay part of my review all my games effort) (short version) You can learn everything about this game in about 30 minutes or less. A good concept that really doesn't work, more of a watch number go up game. At $7 I'd say don't buy it until it's on sale, even then it's honestly just a "watch number go up" there are better free to play games like this like cookie clicker. Truly a grain of sand in the desert of gaming. (no long version needed)

Personally, I find this game confusing, which leads to me being bored due to a lack of understanding of what is going on. I know that a lot of time went into the game, but while it is probably good at showing evolution genetically, it does not do a good job of showing it physically. First off, the plants. Cylinders that grow. I've seen green, dark green, and blue with a hint of green. They spread seeds/spores (sometimes it looks more like spores) that either grow into a plant or disappear for eternity. Sometimes they disappear and you don't know if it's because they died due to old age or a herbivore ate the plant. Speaking of herbivores, they are basically oval-ish things that slide across the ground. I've noticed them either running in circles with one another, seeming to migrate, or pushing themselves against a plant (which I can only assume is them eating). For some reason I mainly find them in an area of the map that I did not put plants in, and they usually die off when my plants are still chilling at the same numbers they were at (or higher) when I added the herbivores. Carnivores, however, I haven't really played with. I was too bored and too annoyed at my herbivores for d…

Intelligent Design: An Evolutionary Sandbox, developed and published by Pill Bug Interactive, is a deeply simulation-focused title that challenges conventional ideas of what a “game” should be. Rather than offering a structured campaign, competitive modes, or clearly defined win conditions, it presents players with a living digital ecosystem governed by genetic inheritance, mutation, and natural selection. The experience places you in the role of a designer-scientist tasked with shaping and observing life within a contained world, functioning more as an experimental laboratory than a traditional entertainment product. At the core of the game lies a fully modeled genetic system that governs every organism within the environment. Creatures are not defined by preset templates but by genomes that dictate their traits—speed, size, energy consumption, reproduction rate, and more. These traits are passed down through generations, occasionally altered by mutation, resulting in evolutionary paths that emerge organically over time. Watching a population adapt to environmental pressures, thrive under favorable conditions, or collapse due to poor design decisions forms the central loop of the…
