About the Game
The makers of Manufactoria return with a new open-ended puzzle game.
"The best game about CPU design that I can imagine" -- Zach Barth (SpaceChem, TIS-100).
- Build complex electronics from a variety of simple components, like Adders, Latches and Multiplexers.
- Travel back to the 60s to Silicon Valley's very first startup, and do your best to keep the whole thing from imploding.
- Solve more than seventy puzzles, from straightforward introductions to building fully functional CPUs.
- Original soundtrack by Craig Barnes, composer for Streets of Rogue and Enyo.

This week is a smaller update; mostly catching up on bugfixes and smaller tweaks, as promised.

Bugfixes
It’s coming up on a month since release, and most of the low-hanging fruit for fixes and improvements are cleared up. The remaining projects are larger, so to give myself time and space to work on them, I’m shifting to one release every two weeks. See you on the next one, and have fun!
View on Steam
Features
- Tweaked a few puzzles’ ideals and tick limits, the latter upward.
- Colored disconnected modules red on the minimap, to help finding isolated ones.
- Clarified ‘Cows’… so to speak.
- OS X uses shift-(cmd-)-z for redo, instead of (cmd-)y.
- SFX for opening/hiding the puzzle description & minimap.
Bugfixes
- The steam leaderboards’ x-axes should be much clearer.
- Non-US keyboards should have working/reasonable hotkeys.
- The ‘Faux-Reg’ achievements will now trigger immediately after beating the puzzle, instead of one puzzle later.
- ‘Maze’ displays its tick limit in the description.
- ‘Finale’’s ideal is beatable, again.
- Secrets no longer missing a perfect sparkle.

This was supposed to be a small release revising areas where people were getting stuck. Instead, I ended up gutting and reworking most of a board. Oops!

Next update should be focused on bugs and tweaks, since there’s a bit of a backlog on those. If there are any small issues that particularly irk you, I’m listening!
View on Steam
Highlights:
- Board 3 (’High Speed’) revised and reworked. Four new puzzles (’Clock’, ’Maze’, ‘Back’, and ‘Splitcount’) added; some uninteresting (’Delay Write’, ‘Stages’) removed; various other fixes and reorderings. If you were stuck here, now’s a good chance to give the board another shot!
- New ‘Hard’ puzzle: ‘Cows’, on board 1. Those who want to get going fast can skip the entire rest of the board, just by beating this puzzle. Everyone likes a challenge, right?
Features:
- 'Ideal’ renamed to ‘Goal’, to reduce confusion when getting better solutions than the ‘ideal’.
- Mousing the bottom-left of modules works as soon as Delay is introduced, rather than only being enabled once the auto-clock is unlocked.
- Added a guide to resizing the game when windowed, in Options.
Fixes:
- Various tests’ time limits changed to be in line with puzzle descriptions.
- Equals modules behave consistently when ‘?’ is passed to an input after the first two.
- Re-added missing UI to Corrupted Memory display.
- Placing a control point under a module no longer causes crashes.
- Added a log file: <GAMEDIR>/log.txt on Windows and Linux, ~/Documents/SZ_Log.txt on OSX.
Next update should be focused on bugs and tweaks, since there’s a bit of a backlog on those. If there are any small issues that particularly irk you, I’m listening!
Fixes a crash when creating Selectors of size 7, and a few smaller issues.
Very sorry for the trouble!

Features:

- New ‘hard’ puzzle “Odds”, in ‘Asides’.
- New ‘nightmare’ puzzle “Parallac”, in ‘Sam’.

- Wire coloring for registers and selectors now works in a hopefully more useful way.

- Play/pause/ff hotkeys changed to “p” in OS X, to not conflict with space-clicking.

Bugfixes:
- Textures should no longer vanish on Windows.

- Discovering a secret while zoomed out now works correctly.
- Non-native fullscreen resolutions work again on OS X. KNOWN ISSUE: cmd-tab is disabled again, sorry!
- Resizing the window while memory is scrolled won’t leave memory ‘stuck’ at an invalid scroll.

- Augends and addends have been reordered.
- You can no longer mouse over a head that doesn’t exist.
