RE4: Otome Edition ver 1.04 now has a patch file for Windows versions downloaded prior to 11/6/2021, 5PM EST. The patch mainly fixes some triggers for the Puzzle, which you would have previously been unable to complete.

• Fixes several instances of Puzzle unlocks not triggering properly
• Adds a "reminder" animation on Puzzle clues so that you can confirm that a condition has been unlocked
• Fixes miscellaneous issues with the title screen and episode select
• Fixes missing sound files in Episode 16
• Adds a prompt on title screen about automatic full screen trigger

The patch has already been incorporated into the full game, both in downloadable and browser. You can also safely download a fresh copy and you'll still have your save files/current unlocks (although you may want to use Episode Select to start fresh rather than use an existing save file, just to be safe). If you run into any issues, please let us know! Have fun!
