About this game

You start out on the surface on a mine shaft, faced with several deposits of valuable ores. You begin building your basic mining rig, harvesting the resources and transporting them via conveyor belts to your storage center. You gather more resources, invest into research & development, discover new techniques and machinery. Your factory grows, your processing chains grow longer, you need to expand.

So you dig down deeper into the earth, discovering new materials and opportunities. All the while your factory must stay humming and busy, so you swap back and forth, adjusting conveyor paths and bottlenecks in the system.

Refine and improve your materials and products further and further, to eventually be able to use highly advanced tech to create the pinnacle of engineering, a computer chip.

Features:
- Procedurally generated world
- 100 different machines
- 100 resources and products
- play-time to your first chip: about 30 hours
- play-time to you feeling there is nothing left to tweak and you can go outside now: infinity

Love this game. It's been scratching that creative/logic balance itch that feels so satisfying. I couldn't find a game like this on Android anywhere. One really annoying bug: my phone likes to try to go to sleep while I am staring at the screen trying to plan stuff. If I try to immediately unlock it, the game kind of freezes on a black screen and then crashes. Thankfully, the game autosaves so I only lose a few minutes of progress. I'd love it if the game prevented sleep or didn't crash.

Definitely scratches the itch of complex resource gathering and processing, building a factory from the bottom up with infinite incremental optimization possibilities. Played through to a computer chip then immediately started a new game. Impressive depth (pun intended) with consistent meaningful incremental progress. Player "quality of life" is a bit mediocre due to absence of useful documentation (either in-game or on the web) and finicky UI requiring lots of taps.

I just started playing so this is sort of a preliminary review. You wouldn't think a game like this would be very challenging, but let me tell you that it certainly is. Trying to coordinate production and where items go without overfilling your storage while also advancing your technology and mining/gathering the various different items is proving to be quite the task! Looking forward to getting farther in this game!
