Opus Magnum

UPDATE: Fix for launch crash on Mac and Linux

This update fixes a launch crash on Mac and Linux introduced in the build from earlier today, caused by an OpenGL-specific shader issue. If you restart Steam it will force this update to be downloaded right away.

UPDATE: Hermit mode, and other small fixes

Today's update adds "hermit mode", in addition to some other small fixes:

  • Adding "hermit mode", which can be turned on in the options menu to hide histograms and leaderboards for players so inclined.
  • When running at a lower-than-native resolution, text should now be slightly more readable.
  • Adding a tutorial tip to the "Stabilized Water" puzzle that teaches how you can right-click and drag to pan any of the in-game UI panels.
  • Repeating product outputs may no longer be rotated.
  • Removing the ability to create repeating reagents in custom puzzles, which are not supported by the game engine.
  • Fixing a crash when loading corrupted solution files, which can sometimes happen when a computer playing the game is abruptly powered off or experiences a system-level crash.

UPDATE: Salt + salt = less disappointment than before

Some small bug fixes for today, including one that Sigmar's Garden fans will hopefully enjoy:

  • You can now match salt with salt in Sigmar's Garden.
  • Improved the written description of the rules in Sigmar's Garden (English only for now).
  • You can now hit Backspace on Macs to delete parts and instructions.
  • You can now hit Ctrl+Backspace to delete text more quickly in the solution and custom puzzle name editors.

UPDATE: Miscellaneous bug fixes

Today's update consists mostly of small bug fixes:

  • When rotating a group of parts with the A/D keys, they will now rotate around the point that you grabbed them by.
  • You can now hold the shift key while scrolling the instruction tray to make it scroll horizontally instead of vertically.
  • Fixed a bug where it was possible to pivot bound atoms held by multiple grippers.
  • Fixed a bug where dragging a part to the far left of the screen to delete it would actually drop it back onto the board.
  • Fixed a bug that caused histogram score indicators to be horribly inaccurate.
  • Fixed a bug where the hidden AZERTY setting in the config file was not honored in the UI.
  • Fixed a bug where non-ASCII characters in solution names were not persisted when saving.
  • Fixed some localization issues, including strings that did not fit in the UI.
  • Added a window icon.
