Thank you! Most you have pointed out are what we are fixing now.
we will update a new version (0.1.1) with Key Rebinding and foreground height reduced in a few days. also a speed up of healing and some small tweaks.
we were using ZXC+Shift and WASD+Shift at beginning, but we found some windows11 use Shift and Ctrl like a switcher at default,you have to press them two times to release it.
