Announcement posted on 4/20/2021:
In early 2020, Hussie officially left What Pumpkin to work on new projects unrelated to Homestuck. In the time since, they completed a new project called Psycholonials. The final chapter of this visual novel was just posted today, and is available on Steam and mobile platforms. While Hussie still retains ownership of the Homestuck IP, they decided last year to fully discontinue their creative involvement in any future Homestuck projects, and instead plans to continue independently developing more projects like Psycholonials.
