0.91 is a massive update that touches every area of the game, drastically improving performance, majorly improving stability, adding dozens upon dozens of little quality-of-life improvements and tweaks, and introducing a few radical new features. For this update, we’ve changed or added over 69,000 lines of code since 0.90.3 across over 1,000 files. It’s been a big effort, but it’s just the start of what’s to come.

We’re very happy with Logic World v0.91. It’s the best version of Logic World yet, and it’s an excellent foundation for the really ambitious updates we’ll be doing next.

Thank you for playing our video game. Enjoy the update. From everyone at Mouse Hat Games, please have a happy holidays, and a wonderful new year!

Fixy Pointy

  • Component positions are now stored as fixed point rather than floating point
  • Component world positions are now calculated in the reference frame of the stack root component

  • When a single component has an output that is supposed to start on, such as the output of an Inverter, the output is now properly rendered as on in the thumbnail
  • Added command: ExportThumbnailCache
  • Added command: RegenerateThumbnailCache
  • Added secret setting: MHG.Secret.Thumbnails.ThumbnailAmbientLighting

  • Fixed flying speed being non-configurable (and way too slow) when the setting “Lock Flight Y Axis” is disabled (#370)
  • Fixed the secret setting MHG.Flying.Secret.AutoEnterNoclipOnStartFlying not even working, and breaking the game in various ways when set to true (#279)

  • Fixed incorrect footstep sounds being played in some situations
  • Fixed new player positions not being applied until all overlay UI is closed


  • Added support for outlining Interactables that are not part of components. This is used for the big clicky button in the test world, which is now outlined when you look at it.
  • Interaction-dragging behavior is now consistent between chairs and standing: when the cursor is moved to be looking at a non-interactable, the interaction ends
  • Added secret setting: MHG.Secret.Interactables.StopInteractionIfLookingAtNonInteractable
  • You can now interact with the same Switch multiple times during one interaction
  • When interacting with a Chair to sit in it, the interaction will now immediately end, instead of continuing while you sit in the chair. Fixes #103


  • Added a “Never” option to the Music Frequency setting
  • Changing Music Frequency will no longer cause music to stop playing (except when setting it to “Never”)
  • Reloading the settings (i.e. by switching settings profiles) no longer causes the music to stop playing
  • Tweaked the default parameters for the fancy pause menu music effects
  • Music is loaded from disk more reliably; fixed music playback issues on some systems (#422)


  • Fixed shared mod .cs files being in shared/ instead of src/shared/ (#341)
  • Fixed mod compilation failing when a mod assembly does not have a path, i.e. when using Harmony mods (#308)
  • Fixed exception when increasing the number of outputs on a component (#457)
  • Fixed InputPeg.AddPhasicLinkWith throwing a NullReferenceException in many cases


  • Dedicated server binaries are now placed in a sub-folder, to keep the root directory clean
  • Periodic server tasks no longer cause a server death spiral if they take too long. This was often presenting when autosave was enabled on a very large world.
  • If the server fails to broadcast its existence on the local network, it will now disable local network broadcasting instead of just crashing
  • Reduced the minimum time between connections to a server from a single IP from 30 seconds to 3 seconds
  • Messages in the server console announcing player leaves/joins are prettier
  • Fixed the server always saving on close even if the server config value SaveOnClose is set to false

SUCC and settings files

  • Error messages about parsing SUCC files are much more helpful, and now contain the file path & line number
  • Various SUCC files, such as settings_master.succ, will now be automatically reloaded and their changes applied when the file is changed on disk
  • Configurable menu data is now stored in the profiled settings files instead of in a separate file for every menu. This means menu configurations now properly work with the settings profile system.
  • The game now updates ___LastLoadedGameVersion in settings_master.succ with the most recently loaded game version every time the game starts
  • Removed config_override files. All server config values are now stored only in config.succ
  • There are far fewer disk writes related to game settings, especially on startup, which should improve startup performance


  • Fixed the game not properly detecting supported network protocols, which was causing various nasty bugs that made the game unplayable in certain network setups or when no external network interfaces are available (#204, #333, #229)
  • Updated Unity version from 2019.4.17f1 to 2019.4.40f1
  • Upgraded server runtime from .NET Core 3.1 to .NET 7.0. For now, .NET 6.0 binaries are also included with the dedicated server.
  • Fixed there being an omega (Ω) in the name of a dll, which prevented the game from working properly in some environments. This also accidentally prevented the game from working if you got it from a particular game pirating service, so uh, you’re welcome, pirates. YAARRRRRR
  • All error messages and APIs are now PG-13
  • Added a system for updating CustomData in saves when the layout for a component’s CustomData changes between versions
  • More kinds of errors in the game loop are now caught and trigger an error screen
  • The PrintUnityEnvironmentInfo command now reports much more information, especially about the system hardware and the graphics API. The information is also now formatted much more nicely.
  • Added command: runtimeinfo
  • Added command: input.ExportSystemKeyNames
  • The Resolution setting is now properly saved as a Vector2Int instead of a string with extraneous data
  • Custom MessagePack formatters now use MessagePack best practices (#259)
  • Fixed the integrated server process not being killed in some cases where it should be (#401)
  • The server now explicitly rejects wire requests between two outputs (previously, it would throw an error if sent one)

Graphics APIs

  • Added OpenGL as an optional graphics API on Windows and MacOS (used with the command-line argument -force-glcore)
  • Added Vulkan as an optional graphics API on Windows and Linux (used with the command-line argument -force-vulkan). Vulkan still has issues on some systems, but once we work those out it will become the default graphics API on Windows & Linux.


  • Linux: fixed mouse button presses sometimes registering as phantom scroll wheel events (#146)
  • Linux: fixed the camera moving when the game window does not have focus and the cursor moves into the game window area (#148)
  • Linux: fixed Action Wheel segments being invisible on Linux OpenGL (#41)
  • MacOS: fixed keybindings in the UI sometimes displaying as empty/blank


  • Changed default offline player names from “Citizen [random number]” to “Bobby #[random number]”, and reduced the max size of the random numbers
  • When taking a screenshot, the screen now flashes grey for one frame (this is a necessary temporary limitation and will be removed in a future release)
  • Added secret setting: MHG.Secret.ScreenshotFlashColor
  • The FPS counter no longer erroneously reports 60FPS for the first second it is enabled (#350)
  • The Resolution setting is now disabled while the game is running in windowed mode, and in general windowed mode is handled much better
  • The 4D option for barrier shader quality is not displayed anymore because it is too slow; however, it can still be used if you enable the secret setting LogicSettings.Secret.ShowHiddenDropdownValues
  • Updated the “Performance Impact” displayed in the settings menu for various graphics settings to be more accurate to the new rendering tech
  • Fixed sometimes not being able to delete sandboxes using the UI (#101)
  • Added a new setting: “Pause on Defocus”. Disabled by default. (#191)
  • Removed intro screen in non-preview versions
  • Added secret setting: MHG.Secret.PreviewsOnly_SkipIntroScreen
  • Added Herobrine
