The new update solved some problems for some people, but apparently it created new problems for other people. So I am rolling back the main version of Braid to the old one until all problems are solved.
Among the problems introduced in the new update:
* The game no longer worked on Windows XP (this was caused by the updating of the game to the new Visual Studio 2013 compiler; Visual Studio now breaks XP compatibility by default).
* The mouse got stuck on the puzzle screen for some players, making puzzles unplayable.
* The game sometimes cannot find a good display mode for some players, whereas it found one before.
I apologize for the inconvenience. It's very hard to know what a Windows game is going to do when released to a large number of people, these days. Developing for Windows now is basically a giant disaster (Windows has become very complicated). The strategy with new versions going forward will be to minimize the amount of Windows functionality that they rely on for the game to be playable (for example, the next release will no longer attempt to go into a fullscreen display mode; it will just render to an offscreen buffer and then stretchblit that to a fullscreen window). Also, I'll test the next update much more thoroughly before releasing it as the main version.
The new update is still live on the beta branch and the password has been taken off the beta branch to make it easy for everyone to get at. New updates will be published on the beta branch until such time as they are determined to be working very well.
Expected features for next update:
* Fix XP compatibility for new version
* Render 'fullscreen' without attempting to switch display modes
* Change the way the game interfaces with the mouse, to minimize problems
Thanks for your patience and again I apologize for any inconvenience.
If the old version of the game doesn't work for you, you might want to try the beta in the meantime and see if that works better.
