Thank you for your feedback.
Yes, we want to prepare more complete animation controller, but we don't have our own animations, so we cannot redistribute them. But you can see them in action in the demo, which as any element can be improved. Anyway, we are working on that part, to forge new cooperations, fill that gap, and make Atavism even more complete.
Server-side physics is on our list for 2020, but we will see what will be on the roadmap presented in February 2020.
We already started working on the next release, which is planned for November, so stay tuned
