Hello and thank you for playing my game!
Well the Discord was busy at one point, with little hangouts and community projects, however it slowly began to slow down as the main members began to get busy and move on. Eventually, along with the discord being less used, the head moderator also had to step down, and since they were a pretty big part of holding the community together, the creator of Bitsy, Alex Ledoux, decided to shut down the discord. It was still around in read-only mode I thought but now I'm not sure where it went...
I should also mention that there is also still a little forum community for bitsy here on itch: https://ledoux.itch.io/bitsy/community
