Opus Magnum

UPDATE: Experimental power-user features
Today's update adds two power-user features, which are mostly hidden for now:

1. Pressing F10 while editing a solution will reload it from disk. This will only be useful to players who are using an external program to edit their solutions, who previously had to restart the game to see their changes show up.

2. Pressing F10 while the GIF recorder is open will switch it into advanced mode, which allows you to manually override when recording starts and stops. If you hit F10 after the solution finishes recording it will default to the automatically detected start and stop frames. If you hit F10 before the solution finishes recording it will cancel recording immediately but require you to set the start and stop values yourself.

If you have any deep thoughts about these changes you should email me (zach@zachtronics.com) and let me know what you think!

UPDATE: Korean translation
Today's update adds a Korean fan translation by Kan_Pungki. Thanks for your hard work!

If you have any feedback about the translation (or anything else, really) you can send me an email (zach@zachtronics.com) and we'll get to the bottom of it.

UPDATE: Small accessibility feature
Today's update adds a hidden setting that causes alt-click to be interpreted as a right-click. It is off by default.

UPDATE: Experimental numpad-based keyboard layout
Today's update adds an experimental numpad-based keyboard layout for players who use their left hand to hold their mouse.

UPDATE: ¡Opus Magnum en español!
¡Opus Magnum ya está disponible en español! Por favor envíeme un correo electrónico (zach@zachtronics.com) si tiene algún comentario o ve algún error.

UPDATE: Improved error messages
Today's update improves some error messages for when the game crashes.

UPDATE: Small change to puzzle file format
Today's update contains a small change to the custom puzzle file format. Nothing to see here, move along...

UPDATE: New journal issue
Today's update adds a third (and presumably final) user-created journal issue that includes two production puzzles. Thanks to everyone who helped out putting these together!

UPDATE: New journal issue
Today's update adds another user-compiled journal issue with five new puzzles designed to challenge your optimization skills.

UPDATE: New journal issue, minor improvements
Today's update adds a new journal issue that was assembled with help from the unofficial Zachtronics Discord server. Thanks everyone!

It also includes a small change to add scores to GIF filenames, and a small fix for a bug where histograms wouldn't be shown if you were subscribed to too many Workshop puzzles.
