Nice.
> can't invest in skill
What did the skill look like? Aside from the icon, did it look anything like below?
> M1 Attack lock-on
Right now you can place [Basic Move] skill in M1 and assign [Basic Attack] skill to another slot, or assign [Basic Move] skill to another hotbar slot and use that to navigate. I'll try to switch up the controls and maybe change some things then.
