A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Today's update fixes a bug where some leaderboards would not show up in the bonus campaign. If you see anything weird in the game, whether or not it's related to leaderboards, please send me an email (zach@zachtronics.com) to let me know! It's been a while since I've updated TIS-100 and I'm always afraid that Unity is going to do something weird.
Boot up your Z5 Powerlance and dial into Last Call BBS, the last game from Zachtronics! The Barkeep’s loaded up his retro computer with a full set of puzzle games for you to download and play. No need to worry about copy protection, they’re all fully cracked and ready to enjoy! Includes eight full games: 20th Century Food Court: Design factories to produce food just like they did over 700 years ago in the 20th century. Keep your costs low and your machines running fast! STEED FORCE Hobby Studio: Assemble robot models based on the anime smash hit Steed Force right on your computer. No sandpaper
Today's update fixes the crash handler and histograms. Nothing else should be affected.
It is so likeZach to release a Zachlike (just a Zach to his friends) about creating drugs in a small Romanian apartment. Molek-Syntez is now squatting on early access, trying to hook you in with the good stuff as you program your molecular synthesiser. Your goal is to turn chemicals into medicines and other substances with “various pharmacological effects”. (more…)
Cor, kids have it easy nowadays. Sure, they’re inheriting a polluted hellhole teetering on the brink of ecological and economic ruin, but look at all the neat games they get to grow up with. Thanks to Zachtronics announcing they’re giving away (nearly) all their games to schools, some of them even get to muck about with fabulously inventive puzzle boxes during their pretend workday. Imagine that! Privileged tykes. (more…)

I reckon most of the RPS Treehouse gang love us some Zachlikes, since well before Alice Prime coined the term in 2016 in reference to Shenzhen I/O. Puzzlemeister Zach Barth likes the term too, as he’s borrowed it for the title of his book. Currently crowdfunding on Kickstarter (500% funded in one day), Zach-Like shows the workings and the processes behind his practical puzzlers. There’s design docs for his major games, sketches and documents for some that never got made and some early design exercises. There’s even some pen-and-paper brainteasers in there, because we’re

This is The Mechanic, where Alex Wiltshire invites developers to discuss the difficult journeys they ve taken to make their games. This time, Exapunks . It s pretty obvious that the excellent Exapunks is a game about hacking. Specifically, it s a game about programming viruses and sending them into networked systems to monkey around with data, set in a great alternative 90s Wired cyberworld of PC cases flashed with black and red decals and zines set in Apple Garamond. For its makers, though, Exapunks is a game about limitations. Its format is the result of hard decisions about how much space y
As anyone who watches their feeds knows, we live in a constantly evolving cyberpunk dystopia. They’re connecting toilets to the internet, for heavens sake. If this Gibsonist world is just too REAL for you, we have put together the ten best videogames about hacking, programming and computing so you can escape into meta-dystopia. Which I’m sure is a much better place. (more…)
Today's update fixes a few bugs that we've been tracking for a while: Fixed a crash caused by OneDrive locking the game's save files. Fixed a crash caused by leaderboard friend scores being too long. Fixed a crash caused by leaderboard friend names having strange characters in them.

The alchemical puzzler Opus Magnum has a few of us at House RPS scratching our heads and shouting “a-ha!” before giddily sharing our twisted contraptions in GIF form. It’s real good, friends. The studio behind it, Zachtronics, is headed by Zach Barth. I spoke to him about the game’s machines, his short stint at Valve, and the reasons he sold his own company. (more…)
Every Monday we send Brendan to the special economic zone of early access and task him with increasing the productivity of the people s republic of videogames. This week, the brain-breaking electronics of SHENZHEN I/O . Some spoilers included. Zach Barth of Zachtronics, who is previously responsible for games like SpaceChem and Infinifactory and who is also definitely a robot, unfurled his new electronics-em-ep this month. In SHENZHEN I/O you play an expert who emigrates to China to work for Longteng Electronics Co. Ltd. That means you ll be building circuits, wiring microprocessors and writin
if(desire_to_program > 10) continue; else return; When I tell people I’m a programmer, I get that look. The glazed eyes, the polite smile, the clear desire to change topic. If I’m lucky, I’ll get pitched on an idea for the next killer mobile app that my conversation partner insists will make us rich; if I’m less lucky, I’ll get wrangled into providing free tech support for the rest of my life. The thing is, though, as impossible as it might sound, programming can be more fun than people realise. Fun enough to warrant
