About Heliopedia

Heliopedia is a game about terraforming planets. Take control of your own solar system, and terraform planets however you see fit!

In the game, you use a faux-realistic chemistry system to find unique combinations and do discoveries. These discoveries are added to the Heliopedia: an in-game encyclopedia, that gives more information about each object. The game follows the story of a friendly sun in the middle of your universe, who gives you new items for the discoveries you make. If you feed it its favorite snack, like coal or ashes, it will spit out a new planet for you to terraform!

Will you create beautiful ocean planets, grass plains and rain forests? Or breed destruction with wildfires, volcanos and thunder storms?

Features
  • 🧪 Pseudo-scientific chemistry system
  • 🪐 Shape planets as you see fit
  • 🌍 11 different main biome types
  • 🔥 Natural disasters like fires, lightning and volcanoes
  • 🐞 Many diverse species of insects, plants, animals and trees
  • 📚 100 encyclopedia entries to find
  • ⏱️ 2-3 hours of play time

This game made me realize that I was never meant to be a god, as only very basic life forms can survive under my care. The highest life forms I managed to sprout were three worms, one snake, and a singular banana tree entirely by chance. This game has some really cool vibes but they are hard to reach when every ecosystem I create collapses into mush.

A very charming and cute game that I am having a blast playing. HOWEVER there are a couple of very big issues. 1- Plants stop producing oxygen once they stop growing in many instances. Not only is this unrealistic, but it can make it damn near impossible to make a stable ecosystem because everything keeps suffocating and dying! Even if making an ecosystem wasn't the intention of the game, I need a stable environment to properly unlock things. Certain environments like ocean planets are IMPOSSIBLE to actually manage because it never makes enough oxygen to sustain animal life, and the lack of animals makes it so nitrates don't return to the ground for plants to survive. 2- limited resources. this isn't the worst thing ever, the game gives you a LOT to work with, but there is still a limited number of oxygen, coal, and ice that can be found in asteroid belts with no way to recover more. You can send stuff to the sun to get deleted, which opens up an opportunity to softlock you 3- Many materials, no way to drop multiple at once. simply being able to drop a group of something at once on a planet would be nice and make it so i DON'T have to spam click it.

[h1] Cute, Reasonably Educational, Great for all ages [/h1] Fun, calming, and a safe game to play with or around small children. Heliopedia is a great addition to anyone's library, whether you have a Doctorates in Biology or are just old enough to grasp the idea of chemistry.

Heliopedia is a quietly ambitious sandbox experience that distills planetary creation, ecology, and experimentation into a compact but surprisingly deep simulation. Developed and published by Sokpop Collective, the game reflects the studio’s signature approach: deceptively simple presentation layered over systems that reward curiosity, patience, and playful tinkering. Rather than offering a structured campaign or explicit goals, it invites players to become cosmic gardeners, shaping entire worlds and observing how life emerges—or collapses—based on the smallest decisions. The premise places you in control of a miniature solar system anchored by a sentient star. By feeding the star various resources, you generate new planets—blank slates ready to be transformed. From there, the experience becomes one of guided experimentation. You adjust atmospheres, seed land and oceans, introduce plants and animals, and manipulate elemental balances, all while trying to coax a planet toward stability. The game doesn’t overwhelm with tutorials; instead, it gently nudges players to learn through cause and effect, turning every success or failure into a lesson about how its systems interlock. What …
