I checked the system settings and there doesn’t seem to be an option to do this. I find it weird having the attack key and jump key right next to each other. There should be a way to change this to your likely just like all other games. If there is my apologies i just can’t find the right way.
I think this is very important topic. Its very annoying to move the char with directions.
IMC has already confirmed that they will have the ability to change hotkeys implemented before the official release.
If you really want to change your hotkeys now, and you are comfortable editing the client XML files, you can open release/hotkey.xml and make any changes you want in there.
Thanks for the answer! and thanks to IMC for such great game.
