About
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.
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...

so glad this is back in development!!
A little bit of fun but ultimately I think it lacks replayability for any but the most hardcore players. A lot of the sliders feel like they had little effect ont he prosperity of the plant based on what random plants actually succeeded (with the exception of the efficiency sliders that always ended up as close to perfect efficiency).
Juego tremendamente aburrido. tiene muy poco que hacer y es solo esperar y esperar y esperar. lo he pillado por 0,79€, y me siento completamente estafado y voy a pedir un reembolso
Very fun! I keep coming back to this game every so years, I love the concept and game-play. Getting a balanced ecosystem finally can feel rewarding. I keep making little weeds that are over efficient or rabbit's that eat up my plants lol
This is a 50/50 kinda thing. It's kinda fun, but more for simulation than it is gaming.
Less of a game and more of a science simulation. The UI is very clunky, graphics simplistic, and an extremely slow pace. Could be entertaining for someone very into evolution and altering genes, but just doesn't provide much entertainment value for me.
Cute little game but seriously lacks optimization. its extremely simple, but after a while the blob assets begin to make my computer sluggish. I also noticed a problem where the herbivores would not reproduce whatsoever.
Absolutely godly concept. Unfortunately as of now, terribly executed. As other reviews have stated, the game is unpolished (to put it generously), and the UI is atrocious. The ambiance is a little unsettling, though given the finish of the game it's hard to say if this is intentional or not. The mechanics are fairly well researched though are not intuitive to the average player in the slightest. Did I mention the UI? A terrible neon green that consumes 90% of the screen. Also, pop-up text on the structures is backwards, and I cannot for the life of me figure out how to rotate the camera. I also could not find the "exit" option in game but that may just be on me. The authors of this game certainly have a vision though, and I'd love to see this game reach its full potential. This niche of games is chronically unexplored, unfortunately. If this game were to build on the eerie god game undertone as well as user mechanics I can see this being a thoroughly enjoyable game.
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 experience. It is less about active moment-to-moment control and more about long-term observation and strategic intervention. Players influence this ecosystem primarily by designing and modifying organisms before introducing them into the world. Genetic editing allows for detailed customization, encouraging experimentation with different trait combinations. A faster species may dominate initially, but it could also exhaust resources too quickly. A larger predator may prove powerful but struggle to sustain its energy demands. The simulation’s complexity means that outcomes are rarely predictable, and even minor genetic adjustments can ripple across generations in unexpected ways. This unpredictability is both the game’s most compelling feature and its greatest challenge, as players must accept that once life is introduced, it evolves beyond direct control. The sandbox structure reinforces the emphasis on experimentation. There are suggested goals and metrics to observe, such as world efficiency and population stability, but they are not presented as rigid objectives. Instead, players are encouraged to ask their own questions: What happens if herbivores evolve extreme speed? Can a balanced ecosystem exist without predators? How resilient is a genetically engineered super-species? The game rewards curiosity and patience, inviting players to treat the environment as a living research project rather than a challenge to conquer. Visually, Intelligent Design adopts a minimalist aesthetic. Landscapes and organisms are rendered in a functional style that prioritizes clarity over spectacle. This simplicity reinforces the simulation’s scientific tone, though it may feel sparse to players accustomed to visually rich sandbox titles. The interface, while comprehensive, can initially appear dense and unintuitive. Much of the experience involves reading data, analyzing genetic traits, and interpreting population statistics. For players comfortable with analytical tools, this depth adds authenticity. For others, it may create a barrier to entry. The pacing is deliberate and often slow. Evolution unfolds across simulated generations, meaning that meaningful changes may take time to manifest. The game does not rush progress or artificially accelerate results for dramatic effect. This measured tempo enhances realism but requires patience and sustained engagement. It is a title that benefits from observation and reflection rather than rapid interaction, making it particularly suited to players who enjoy systems-driven gameplay and long-term strategy. Community reception reflects this specialized appeal. Players fascinated by biology, emergent systems, and complex simulations often praise the game’s ambition and authenticity. They highlight the satisfaction of witnessing unpredictable evolutionary outcomes and appreciate the freedom to experiment without rigid constraints. Conversely, some players find the interface cumbersome and the lack of traditional gameplay elements limiting. The absence of structured narrative progression or immediate rewards can make the experience feel more like a digital experiment than a conventional game. Ultimately, Intelligent Design: An Evolutionary Sandbox occupies a unique niche within the simulation genre. It is less concerned with entertainment spectacle and more focused on modeling dynamic systems of life and adaptation. Its strength lies in its commitment to authentic genetic simulation and emergent behavior, offering a playground for experimentation that few games attempt. While its complexity and slow pacing may not appeal to every player, those drawn to scientific curiosity and systemic depth will find it a fascinating environment in which to observe, design, and reflect on the mechanics of evolution itself. Rating: 5/10
First off, the tutorial sucks and doesn't walk you through things. Next its ugly. Thirdly it get old, like, really fast. Theres not much fun to be had and you just look at blobs of black, green, blue, etc. I know I only played it for a short time, but it wasn't even entertaining to watch while you did nothing for 10 mins.
