Howdy!
We have accomplished much in the last two weeks we would like to share! To fill the next two weeks we will be releasing additional gifs to provide more visual context before our next devlog update.

New Features
Oxygen:

• We have implemented an oxygen system that your workers need to survive! The maximum amount of oxygen you can have at any one time is determined by how large you dig out your base. Doing this will spread your precious resource thin, so you must build additional oxygen generators to ensure the room stays breathable in conjunction with producing more workers. Oxygen restricts you from cloning continuously, and will become a major concern if you dig into a large cavern unprepared.

Energy:

• An energy system has been implemented that your buildings need to run. Power can be created in generators and stores in energy storage, which obviously boosts the maximum energy you can store. Different buildings draw different amounts, and at different times, so you have to be sure you have enough production and storage to prevent critical systems like your oxygen from shutting off which will kill off your workers!

Zooming:

• You can now zoom in and out in game. UI scales and functions as expected while doing so.

Click and Drag:

• Whenever you do pretty much anything now, you can click and drag to select whatever tiles you want acted on. Below is mining with this enabled.

Selecting:

• You can now select any tile. This will be greatly expanded on in the future, currently this can be used to refund buildings and improvements you don’t want, as well as boosting the priority of work you want done at locations on the map.

Building Changes:

• Functionality for different size and shape buildings has been implemented. Buildings can now occupy any tiles in a 3x3 area. Each tile of a building must be built separately which feels quite satisfying.

Buildings
Cloner:

• Consumes a large amount of energy to produce a new worker.

Storage:

• A structure that increases the maximum amount of resources that you can gather.

Beacon:

• Caves are dark. This is a really bright light you can construct to make a large chunk of cave more visible.

Nodes:

• These guys will be of tremendous importance in the future, but we have some of their basic functionality right now. You’ll need to keep these babies connected as any break in the chain will cause those cut off to shut off. They produce light, heat, and even a little oxygen at little cost to you.

Looking Ahead
There are a few things planned for the next two weeks:

• Simple tileset to improve dramatically on the two tiles we are using now.

• More functionality for nodes, upgrades, etc

• Power states for buildings, ability to shut on and off

• Balancing and expanding on the energy system

• Beginning of rework of world generation and groundwork for expansion of the variety of wall types and terrain you will come across.

Thanks everyone for supporting us, give us a follow here on GameJolt if you are interested in future updates, and don’t forget to follow us on Twitter!

TLDR; Workers need to breath, you need energy to make air, there’s some different things workers can build while they breathe, we’ll have better looking screenshots soon, I swear!
