Last Call BBS - The last game by Zachtronics!
SpaceChem - krispykrem
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 required!
  • X’BPGH: The Forbidden Path: Enter a cursed world and create bizarre flesh sculptures in exchange for eternal life. The master is pleased… but can you trust him?
  • Sawayama Solitaire: It wouldn’t be a Zachtronics release without a brand-new solitaire game. This time it’s a fresh take on Klondike, the “classic” solitaire variant.
  • Dungeons & Diagrams: Try your hand at these beguiling tile-based logic puzzles. Can you map out the dungeons and steal all the treasure?
  • ChipWizard™ Professional: Build integrated circuits using wires, transistors, and capacitors. Wait a second, is this a game or a CAD program?
  • HACK*MATCH: The tile-matching minigame from EXAPUNKS, completely remastered with a single player campaign and local head-to-head multiplayer (with Steam Remote Play support).
  • Kabufuda Solitaire: Create matching sets of Japanese kabufuda cards in this retro-demake of the challenging original solitaire game that debuted in Eliza.

SpaceChem - krispykrem
Today's update fixes a minor bug where typing a forward slash into a text field would paste the contents of your clipboard instead, in addition to some tweaks to make the "mirror vertically" feature more intelligent.

UPDATE: 64-bit Mac Support (v1016)
SpaceChem - krispykrem
Today's update brings SpaceChem into the future with an upgrade from SDL 1.2 to SDL 2.0 and 64-bit builds for macOS so that the game now runs on macOS Catalina. It looks like it also contains a few fixes for obscure crashes and scroll wheel support for some of the game's UI.

Satisfactory review (early access)
SpaceChem - contact@rockpapershotgun.com (Brendan Caldwell)

There it is, the trans-planetary pipeline. One long tube of metal scarring a rural alien planet. It brings coal and water to my power stations, and electricity to my factories. It has taken a day of planning, construction and pumping. Now, the pipeline stands before me, a snaking behemoth of energy consumption. Suddenly, a thought comes. Why didn’t I just build coal stations next to the vein? I could have stretched a cheap wire across the planet, instead of a kilometre-long death pipe.

This is Satisfactory, a cracking first-person factory-builder that’s been in early access on Epic for a while. It’s coming to Steam today, so RPS management dispatched me to inspect the game’s machinery and ruin the extraterrestrial idyll with smog and incompetence. They sent the right person.

MOLEK-SYNTEZ is a new Zachtronics game about making drugs in a cold Romanian apartment
SpaceChem - contact@rockpapershotgun.com (Craig Pearson)

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”.

Zach-Like comes to Steam free with loads of game-like extras
SpaceChem - contact@rockpapershotgun.com (Dominic Tarason)

Zach-like, the book about Zachlikes by Zach Barth, creator of the genre, is now free albeit notably less papery now. Zachtronics’s previously Kickstarter-exclusive book was a collection of design documents from the creator of Spacechem, Opus Magnum, Infinifactory and many more, showing just how he engineers his puzzles. Now anyone can read a digital version for free, and it comes bundled with a pile of his early browser games, unreleased prototypes, and even a card game if you’ve got printer ink to burn. Grab it free on Steam. I feel smarter just having it on my PC.

UPDATE: SpaceChem community update (v1013)
SpaceChem - krispykrem
Can you believe it's been over eight years since SpaceChem first launched? Today we're releasing a community-driven update featuring a host of bug fixes, improvements, and new journal puzzles. Special thanks to 12345ieee and Csaboka, who did most of the actual work for this update.
  • Added a bunch of new user-created puzzles to ResearchNet.
  • Added a right-click menu to the inside of reactors with options to swap colors, mirror the program, and reset the contents of the reactor.
  • Added an option to the options menu to show bonder priority in reactors.
  • Improved the performance of the fastest playback speed in non-defense puzzles so that it now runs as fast as your computer can handle.
  • Enabled all of the "Greek symbol elements" in ResearchNet puzzles.
  • Added the ability to add bonds to the "unknown element" symbol in molecule annotations.
  • Changed reactors to be processed in topological order so that there is no longer a need to consider "reactor priority" when optimizing your solutions.
  • Changed the video recording logic to prevent videos from being too short or too long.
  • Fixed a bug where random inputs varied depending on your operating system. The new behavior should be identical to the old behavior for Windows users. Impossible scores will be removed from leaderboards in the coming days.
  • Fixed some obscure bugs that have somehow persisted over the years, including missed collisions, asymmetrical collisions, "molecule smashing," and "telekinesis."
  • Fixed a bug where you could delete symbols while a solution was running.
  • Fixed a bug where leaderboards would sometimes be empty for players with computers set to non-English locales.
  • Fixed a bug where wrong outputs were sometimes accepted.
  • Fixed a bug where you could lose after winning a defense puzzle.
  • Fixed a broken YouTube link for the optional tutorial video.
  • Removed all YouTube upload functionality from the game.
