The Oddities of the Planet

As you spoiling the planet of its resources

Content Overview

Energy Pool

It all starts from here: the Energy Pool. The building processes Power Slugs into the main resource: Energy Liquid.



The infuser impermeates resources with Liquid Energy to create new materials with new and different properties

The Building is composed by an Inlet, where the resources are manually provided, and a container where Energy Drink can be poured on the resource inputed.


Here's a Demo showcasing the building in action LINK

Bio Brewery

The Bio Brewery uses Mycelia spores to sollicitate the spontaneous growth of flora using Slimy Compost as a Fertilizer bursting into fruits.

The Building takes Water and Slimy Compost as inputs and it requires a constant supply:

Every minute the Bio Brewery will drain 90 Water and Use 1 Slimy Compost.

Every 5 minutes a certain amount of Berries, Nuts and Mycelia will be generated that can be manually picked up.

Every 10 minutes the Bio Brewery will change its growth stage, producing more fruits the further the stage.

The process will end at 50 minutes mark at which point the process will end and start from stage 0 (once the proper input are provided)


To Do List

  • Automation!
  • Manipulation of the liquid Energy
  • And More!

  • Comments

    Hey everyone, hope you're doing well. In this update we finally deliver some deserved automation through the Fluid Press.

    The machine is simple on its own and doesn't have a UI (i don't think it needs it as it is straightforward).

    Above all the Modular Storage makes its appereance: it's a really complex building as it can be customized through research and through its UI.

    Did i tell you already it has a built-in item filtering? You can decide which item goes where and also limit the stacks of item you wish to utilize for your storage!

    I've also changed the UI of both the Artifact Radar and the Octahedrons. The Discovery System received a bit of revamping in the background so that it will be easier for me to implement new rewards.

    For now chances are you won't be able to fully upgrade the Modular Storage (yet) as there won't be enough resources, but small updates will be delivered as i am able to find more suitable locations for more Octahedrons.

    Hope you will enjoy this update. Thanks always for your support.
