A new update v1.1.0 has just released. This includes a lot of final support changes for Alexander's upcoming DLC and a new sprite for Mrs. Gabriella Dallarosa (Sebastian, Alexander, and Isabella's mother). Brandon's patch has also been updated to include this new sprite.
You will need this latest update to play the DLC and Brandon's update.
Alexander's DLC is releasing on Feb 19th, 2024.
Don't forget! A few choices in Alexander's DLC are locked behind the secret character's route, so make sure you've completed that character's route by release!
