[b]Update content for August 2nd: Added keyboard controls[/b] Dear Dr. Chatelet, in order to facilitate you in performing bloodletting and amputation surgeries, and save more patients, we have added keyboard controls. 1、Bloodletting treatment can now be controlled using the space bar on your keyboard for preparation and making the incision; 2、For amputation surgeries, use the A/D keys on your keyboard to control the amputation.
