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.

UPDATE: Minor bug fixes
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.

UPDATE: More bug fixes (v1015)
SpaceChem - krispykrem
Today's update is all bug fixes, brought over from the game's unofficial "community edition":
  • Fixed a Windows-only display bug when using a high-DPI monitor.
  • Fixed an exploit where you could disconnect a pipe from its reactor.
  • Fixed a crash when loading invalid ResearchNet puzzles with negative counts.
  • Fixed a crash when displaying text with an ellipsis but not enough space to fit it.
  • Fixed a bug in undo/redo with cloned reactors.
  • Fixed a crash when pressing Ctrl-Z while dragging a pipe.
  • Fixed a bug where input distributions were reset when opening windows in ResearchNet.

UPDATE: Bug fixes (v1014)

Today's update includes the following:
  • Fixed a crash when starting a pipeline with too many reactors.
  • Removed impossible scores from the histograms for the "Swapite" journal puzzle.
  • Bumped the version number from 1013 to 1014.
When things settle down with these changes I'll upload a build to non-Steam stores as well.

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.

UPDATE: SpaceChem is back on Mac!
SpaceChem - krispykrem
After a few years of SpaceChem not being officially supported on Mac, we've finally gotten around to getting it working again! It ought to work out of the box for everyone now, and not require Mono to be installed separately or anything like that.

If you experience anything weird please send me an email (zach@zachtronics.com).
