That's it! 145,000 downloads later, Portal: Prelude 1.1.0 is released!
This new version is shipped with more than 80 bug fixes and additions, along with slightly easier/less frustrating first levels. Warning! Savegames are NOT compatible. Your progress with chapters unlocking is saved, but not savegames.
Both the Portal: Prelude 1.1.0 complete installer and the 1.0.0 to 1.1.0 cumulative patch are released! Head up to the download page, and enjoy! For the moment, only a few mirrors are up to date. More of them will appear in the next days/weeks.
Of course, the goal was not to rework whole parts of the game after the release, but we tweaked a lot of chambers, all of them in fact. Especially, the first levels to avoid immediate frustration (that was our primary goal). Then, we used all the criticisms we received to build a better game. All the levels/challenges were slightly modified, that's why the patch is so huge.
