TurboWarp made an announcement about unshared projects on May 8th, which was scary at first, but now they rewrote the documentation. You can read it here: https://docs.turbowarp.org/unshared-projects
The purpose of us using TurboWarp is mainly because we want our games to be advanced and high quality instead of using normal Scratch which has significant amount of limitations. And because of this announcement was made, we have 3 back-up plans just in case. We can continue our work as normal since nothing has changed, but if this new Scratch API changes released, we need to use one of our back-up plans. So, DO NOT worry too much about this. To understand what I'm talking about, read the text in the project.
