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.

- 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

This game is TOO good! For a week or two, I could barely put it down. :-P But it's not for everyone. There's no combat, no story, not even any puzzles in the conventional sense. The fun of the game is in building an intricate construction, watching it run, tinkering to make it more efficient, and unlocking new functionality as a result. Sort of like SpaceChem or Human Resource Machine. My main criticism is that the ending feels very unsatisfying, perhaps because of the total lack of story.

Really good game let down by a complete lack of documentation or glossary. For example, trying to find out how to make lubricant, only to find that it's not even showing on the tech tree yet. Concept is fantastic and gameplay is deep - I just wish there was some further gloss to it, or maybe a sequel.

A neat logistics puzzle, with a better UI than I've seen in other mobile games that try to do the same kind of thing. I'm still too early on in the progression to comment on how complex the logistics get, but at least the (intentional) early restrictions are fun to work around. The developer is very responsive. I had an issue with the game requiring external storage permissions, and they had an update with a fix the next day.
