Hello there!
After yesterday's Beta version update, we have received many reports and feedback from our fans.
Among those reports, many were related to controlling the length of the Chain Arm (Spacebar).
A temporary fix for this issue is to reset your key settings in the menu.
We will fix this issue in an update soon.
Furthermore, we are very aware that the Beta version lacks polish in many parts.
We will implement the feedbacks we have received for the official update.
Thank you.
