Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Sep 11 → 1.33/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Эта игра показывает, что даже сидя в яме и имея только жаренные батарейки можно проложить интернет лучше, чем у ростелекома
It's a real slog with no payoff. You learn a whole automation system just to never be challenged on using it well, it's extremely repetitive both moment to moment and in terms of the kinds of environments you encounter, and the plot just kind of happens out of nowhere having nothing to do with what you've been doing in the gameplay. I wanted to go back and collect whatever achievements I missed, but in several areas I'm now being killed by something invisible for reasons I can't understand.

It's fun for a while, but there is no real exploration of the puzzle mechanics or story. It's just, learn the basic mechanisms and then repeat the same puzzles 12+ times in the same areas slightly offset from each other. This game has SO much potential and it hurts that they never expand on it.
The strongest part of this game is the first couple hours when you are working out how the networking functions and building your logic and loops. At this point of the game, it is a strong idler/incremental as you gain more and more money in order to buy upgrades and dig further. This part of the game falls apart in the midgame when the "horror" aspects start to influence your world and permanently hamper your network. This culminates in a really terrible endgame/final boss. It was overall still a pretty enjoyable experience even though I tapped out during the final boss fight and didn't technically finish it.
This is such a gem of a little game and I find myself coming back to it regularly whenever I find myself looking for something to play but don't know what I want to play. As others have mentioned, the monsters and final boss are just kinda meh, but the actual networking aspect of the game is great. It's not so complicated like factorio where staring at it for too long will melt your brain, but not so easy that it's completely braindead. It finds a nice balance between the two and it even finds a way to where you can slap things together and make it work, or hyper optimize your network so that all packets are going where they need to go. If you're looking for an interesting game with light/medium puzzles with a hint of horror, it's absolutely well worth the asking price. To the dev, if you're reading this. I really hope you continue your work on this game. I'd love to see more endpoints, more POI's. I'd also love to see a dedicated light object not connected to the network, object snapping, and a final drill upgrade that lets you place flat metal surfaces and maybe even some unique tiles to help with organizing your network. I saw on your website that you're working on a new game as well and I'm looking forward to checking it out.
At first I thought this would be another "work simulator" type game, but it's actually a delightful puzzle game, with some great retro esthetics. The final puzzle absolutely stumped me, it's such a tangled mess of wires. At times, the "horror" mechanics were grating, and I wanted to get back to expanding my network, but you can turn hostile monsters off in the settings if you want. The leaderboard is reminiscent of Zachtronics games, and you are encouraged to learn the tools and mechanics to improve your score (but there's no rush, and it pays to explore rather than obsess over optimization). By far the standout feature is the retro visual and sound design, it's a great example of the style.
I can finally live my dream of maintaining a vast network of machinery whilst living in an underground cave. I would be willing to pay upwards of $80 USD for a version of this game that uses procedural mapgen.
For the cost of a meal deal at Dunkin this game is worth it, it had me drawing out optimized sub net architectures and that was pretty fun. Personally though, I didn't love the game loop I found myself in. I feel like this game has a very strong core mechanic that should have been focused on more, because everything else just felt annoying to deal with when I just wanted to get back to making an optimized system. Still, very worth it if you have 8+ hours to kill and a notepad
Let me be clear, for this price, you can argue that this game is worth it. As of now, it might be worth playing around the starting location for a few hours and move on with life. It's a cool concept with "game" around it. If it was a 2D polished game for the same price, it'd be probably better. Game is missing critical QOL features that could be added as late game upgrades - ability to TP to the mainframes - some sort of night vision - unlimited sprint, etc These would make the game's pacing much better towards the end. There are also quite a few half-baked features like hackers, quests, trading. Unfortunately, I cannot recommend it as a complete game as doesn’t respect the player’s time.
"I feel truly alone in these tunnels" WELL THAT MAKES ONE OF US
