Updates to Puzzle Agent have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:
Render Layer Issues on NVidia 400 Series Video Cards Fixes the graphics bug that blocked players at the first snowmobile puzzle.
Text Not Displaying on Non-English OS: Fixes issue that caused all in-game text to disappear if the game was running on an OS set to any language but English.
Two puzzles— Maw of Madness and Hydraulic Headache had additional rules text added that clarifies the requirements of the puzzles.
Room Key Confusion: In the original version, the NINE text was much bigger and vertically-oriented. In this updated version it appears smaller, and is horizontal. The essence of the puzzle is still the same, but the changes make it more straightforward to figure out.
Cut Your Losses: In the original version, the goal was to draw a line connecting all the players that intersected with every pane of glass. In the updated version, the goal is identical to the first football puzzle: Draw a line connecting all the players that avoids every pane of glass.
