This is a medical advice. Seriously ...
Keyboard are not so precise with direction, so when you explore the world, (and you DO !), you hold down the mouse button to avoid go&stop, and move the pointer around the character for the direction.
As many ressources are rare, you spent hours to run around ...
It put a lot of pression on the wrist ; and it's BAD.
You should definitively add an auto-run Key. In this mode the character follow the mouse pointer without clicking.
As soon as you click, or press again the key, you exit this mode.
I am afraid without this addition, i won't play this (very addictive) game :-(
Hope others share my feeling ; please support for this key addition.
