Description

[OUTDATED NAME] The main community for upcoming Sonic asym Castaway Dreams, previously SSZ, featuring a ton of the main Sonic cast plus some of our own creative twists! This game's development has been moved to Unity, but communication here will still be checked on from time to time. The game is currently looking for team members as we slowly begin development, so feel free to send us a message if you want to try out for the dev team! We appreciate all the support and hope we can live up to the excitement we give you all throughout this game's creation!

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
